+This is the popt command line option parsing library. While it is similiar
+to getopt(3), it contains a number of enhancements, including:
+
+	1) popt is fully reentrant
+	2) popt can parse arbitrary argv[] style arrays while 
+	   getopt(2) makes this quite difficult
+	3) popt allows users to alias command line arguments
+	4) popt provides convience functions for parsing strings
+	   into argv[] style arrays
+
+popt is used by rpm, the Red Hat install program, and many other Red Hat
+utilities, all of which provide excellent examples of how to use popt. 
+Complete documentation on popt is available in popt.ps (included in this
+tarball), which is excerpted with permission from the book "Linux
+Application Development" by Michael K. Johnson and Erik Troan (availble
+from Addison Wesley in May, 1998).
+
+Comments on popt should be addressed to ewt@redhat.com.

+/*
+  a replacement for opendir/readdir/telldir/seekdir/closedir for BSD systems
+
+  This is needed because the existing directory handling in FreeBSD
+  and OpenBSD (and possibly NetBSD) doesn't correctly handle unlink()
+  on files in a directory where telldir() has been used. On a block
+  boundary it will occasionally miss a file when seekdir() is used to
+  return to a position previously recorded with telldir().
+
+  This also fixes a severe performance and memory usage problem with
+  telldir() on BSD systems. Each call to telldir() in BSD adds an
+  entry to a linked list, and those entries are cleaned up on
+  closedir(). This means with a large directory closedir() can take an
+  arbitrary amount of time, causing network timeouts as millions of
+  telldir() entries are freed
+
+  Note! This replacement code is not portable. It relies on getdents()
+  always leaving the file descriptor at a seek offset that is a
+  multiple of DIR_BUF_SIZE. If the code detects that this doesn't
+  happen then it will abort(). It also does not handle directories
+  with offsets larger than can be stored in a long,
+
+  This code is available under other free software licenses as
+  well. Contact the author.

+/*
+  a replacement for opendir/readdir/telldir/seekdir/closedir for BSD
+  systems using getdirentries
+
+  This is needed because the existing directory handling in FreeBSD
+  and OpenBSD (and possibly NetBSD) doesn't correctly handle unlink()
+  on files in a directory where telldir() has been used. On a block
+  boundary it will occasionally miss a file when seekdir() is used to
+  return to a position previously recorded with telldir().
+
+  This also fixes a severe performance and memory usage problem with
+  telldir() on BSD systems. Each call to telldir() in BSD adds an
+  entry to a linked list, and those entries are cleaned up on
+  closedir(). This means with a large directory closedir() can take an
+  arbitrary amount of time, causing network timeouts as millions of
+  telldir() entries are freed
+
+  Note! This replacement code is not portable. It relies on
+  getdirentries() always leaving the file descriptor at a seek offset
+  that is a multiple of DIR_BUF_SIZE. If the code detects that this
+  doesn't happen then it will abort(). It also does not handle
+  directories with offsets larger than can be stored in a long,
+
+  This code is available under other free software licenses as
+  well. Contact the author.

+ * the version here does not include floating point...
+ *
+ * snprintf() is used instead of sprintf() as it does limit checks
+ * for string length.  This covers a nasty loophole.
+ *
+ * The other functions are there to prevent NULL pointers from
+ * causing nast effects.
+ *
+ * More Recently:
+ *  Brandon Long <blong@fiction.net> 9/15/96 for mutt 0.43
+ *  This was ugly.  It is still ugly.  I opted out of floating point
+ *  numbers, but the formatter understands just about everything
+ *  from the normal C string format, at least as far as I can tell from
+ *  the Solaris 2.5 printf(3S) man page.
+ *
+ *  Brandon Long <blong@fiction.net> 10/22/97 for mutt 0.87.1
+ *    Ok, added some minimal floating point support, which means this
+ *    probably requires libm on most operating systems.  Don't yet
+ *    support the exponent (e,E) and sigfig (g,G).  Also, fmtint()
+ *    was pretty badly broken, it just wasn't being exercised in ways
+ *    which showed it, so that's been fixed.  Also, formated the code
+ *    to mutt conventions, and removed dead code left over from the
+ *    original.  Also, there is now a builtin-test, just compile with:
+ *           gcc -DTEST_SNPRINTF -o snprintf snprintf.c -lm
+ *    and run snprintf for results.
+ * 
+ *  Thomas Roessler <roessler@guug.de> 01/27/98 for mutt 0.89i
+ *    The PGP code was using unsigned hexadecimal formats. 
+ *    Unfortunately, unsigned formats simply didn't work.
+ *
+ *  Michael Elkins <me@cs.hmc.edu> 03/05/98 for mutt 0.90.8
+ *    The original code assumed that both snprintf() and vsnprintf() were
+ *    missing.  Some systems only have snprintf() but not vsnprintf(), so
+ *    the code is now broken down under HAVE_SNPRINTF and HAVE_VSNPRINTF.
+ *
+ *  Andrew Tridgell (tridge@samba.org) Oct 1998
+ *    fixed handling of %.0f
+ *    added test for HAVE_LONG_DOUBLE
+ *
+ * tridge@samba.org, idra@samba.org, April 2001
+ *    got rid of fcvt code (twas buggy and made testing harder)
+ *    added C99 semantics
+ *
+ * date: 2002/12/19 19:56:31;  author: herb;  state: Exp;  lines: +2 -0
+ * actually print args for %g and %e
+ * 
+ * date: 2002/06/03 13:37:52;  author: jmcd;  state: Exp;  lines: +8 -0
+ * Since includes.h isn't included here, VA_COPY has to be defined here.  I don't
+ * see any include file that is guaranteed to be here, so I'm defining it
+ * locally.  Fixes AIX and Solaris builds.
+ * 
+ * date: 2002/06/03 03:07:24;  author: tridge;  state: Exp;  lines: +5 -13
+ * put the ifdef for HAVE_VA_COPY in one place rather than in lots of
+ * functions
+ * 
+ * date: 2002/05/17 14:51:22;  author: jmcd;  state: Exp;  lines: +21 -4
+ * Fix usage of va_list passed as an arg.  Use __va_copy before using it
+ * when it exists.
+ * 
+ * date: 2002/04/16 22:38:04;  author: idra;  state: Exp;  lines: +20 -14
+ * Fix incorrect zpadlen handling in fmtfp.
+ * Thanks to Ollie Oldham <ollie.oldham@metro-optix.com> for spotting it.
+ * few mods to make it easier to compile the tests.
+ * addedd the "Ollie" test to the floating point ones.
+ *
+ * Martin Pool (mbp@samba.org) April 2003
+ *    Remove NO_CONFIG_H so that the test case can be built within a source
+ *    tree with less trouble.
+ *    Remove unnecessary SAFE_FREE() definition.
+ *
+ * Martin Pool (mbp@samba.org) May 2003
+ *    Put in a prototype for dummy_snprintf() to quiet compiler warnings.
+ *
+ *    Move #endif to make sure VA_COPY, LDOUBLE, etc are defined even
+ *    if the C library has some snprintf functions already.
+ *
+ * Darren Tucker (dtucker@zip.com.au) 2005
+ *    Fix bug allowing read overruns of the source string with "%.*s"
+ *    Usually harmless unless the read runs outside the process' allocation
+ *    (eg if your malloc does guard pages) in which case it will segfault.
+ *    From OpenSSH.  Also added test for same.
+ *
+ * Simo Sorce (idra@samba.org) Jan 2006
+ * 
+ *    Add support for position independent parameters 
+ *    fix fmtstr now it conforms to sprintf wrt min.max
+ *

+    <para>
+      If you are used to talloc from Samba3 then please read this
+      carefully, as talloc has changed a lot.
+    </para>
+    <para>
+      The new talloc is a hierarchical, reference counted memory pool
+      system with destructors.	Quite a mouthful really, but not too bad
+      once you get used to it.
+    </para>
+    <para>
+      Perhaps the biggest change from Samba3 is that there is no
+      distinction between a "talloc context" and a "talloc pointer".  Any
+      pointer returned from talloc() is itself a valid talloc context. 
+      This means you can do this:
+    </para>
+    <programlisting>
+    struct foo *X = talloc(mem_ctx, struct foo);
+    X->name = talloc_strdup(X, "foo");
+    </programlisting>
+    <para>
+      and the pointer <literal role="code">X-&gt;name</literal>
+      would be a "child" of the talloc context <literal
+      role="code">X</literal> which is itself a child of
+      <literal role="code">mem_ctx</literal>.  So if you do
+      <literal role="code">talloc_free(mem_ctx)</literal> then
+      it is all destroyed, whereas if you do <literal
+      role="code">talloc_free(X)</literal> then just <literal
+      role="code">X</literal> and <literal
+      role="code">X-&gt;name</literal> are destroyed, and if
+      you do <literal
+      role="code">talloc_free(X-&gt;name)</literal> then just
+      the name element of <literal role="code">X</literal> is
+      destroyed.
+    </para>
+    <para>
+      If you think about this, then what this effectively gives you is an
+      n-ary tree, where you can free any part of the tree with
+      talloc_free().
+    </para>
+    <para>
+      If you find this confusing, then I suggest you run the <literal
+      role="code">testsuite</literal> program to watch talloc
+      in action.  You may also like to add your own tests to <literal
+      role="code">testsuite.c</literal> to clarify how some
+      particular situation is handled.
+    </para>

+  <refsect1><title>TALLOC API</title>
+    <para>
+      The following is a complete guide to the talloc API. Read it all at
+      least twice.
+    </para>
+    <refsect2><title>(type *)talloc(const void *ctx, type);</title>
+        <para>
+	  The talloc() macro is the core of the talloc library.  It takes a
+	  memory <emphasis role="italic">ctx</emphasis> and a <emphasis
+	  role="italic">type</emphasis>, and returns a pointer to a new
+	  area of memory of the given <emphasis
+	  role="italic">type</emphasis>.
+        </para>
+        <para>
+	  The returned pointer is itself a talloc context, so you can use
+	  it as the <emphasis role="italic">ctx</emphasis> argument to more
+	  calls to talloc() if you wish.
+        </para>
+        <para>
+	  The returned pointer is a "child" of the supplied context.  This
+	  means that if you talloc_free() the <emphasis
+	  role="italic">ctx</emphasis> then the new child disappears as
+	  well.  Alternatively you can free just the child.
+        </para>
+        <para>
+	  The <emphasis role="italic">ctx</emphasis> argument to talloc()
+	  can be NULL, in which case a new top level context is created.
+        </para>
+    </refsect2>
+    <refsect2><title>void *talloc_size(const void *ctx, size_t size);</title>
+        <para>
+	  The function talloc_size() should be used when you don't have a
+	  convenient type to pass to talloc().	Unlike talloc(), it is not
+	  type safe (as it returns a void *), so you are on your own for
+	  type checking.
+        </para>
+    </refsect2>
+    <refsect2><title>(typeof(ptr)) talloc_ptrtype(const void *ctx, ptr);</title>
+        <para>
+	  The talloc_ptrtype() macro should be used when you have a pointer and
+	  want to allocate memory to point at with this pointer. When compiling
+	  with gcc >= 3 it is typesafe. Note this is a wrapper of talloc_size()
+	  and talloc_get_name() will return the current location in the source file.
+	  and not the type.
+        </para>
+    </refsect2>
+    <refsect2><title>int talloc_free(void *ptr);</title>
+        <para>
+	  The talloc_free() function frees a piece of talloc memory, and
+	  all its children.  You can call talloc_free() on any pointer
+	  returned by talloc().
+        </para>
+        <para>
+	  The return value of talloc_free() indicates success or failure,
+	  with 0 returned for success and -1 for failure.  The only
+	  possible failure condition is if <emphasis
+	  role="italic">ptr</emphasis> had a destructor attached to it and
+	  the destructor returned -1.  See <link
+	  linkend="talloc_set_destructor"><quote>talloc_set_destructor()</quote></link>
+	  for details on destructors.
+        </para>
+        <para>
+	  If this pointer has an additional parent when talloc_free() is
+	  called then the memory is not actually released, but instead the
+	  most recently established parent is destroyed.  See <link
+	  linkend="talloc_reference"><quote>talloc_reference()</quote></link>
+	  for details on establishing additional parents.
+        </para>
+        <para>
+	  For more control on which parent is removed, see <link
+	  linkend="talloc_unlink"><quote>talloc_unlink()</quote></link>.
+        </para>
+        <para>
+	  talloc_free() operates recursively on its children.
+        </para>
+    </refsect2>
+    <refsect2 id="talloc_reference"><title>void *talloc_reference(const void *ctx, const void *ptr);</title>
+        <para>
+	  The talloc_reference() function makes <emphasis
+	  role="italic">ctx</emphasis> an additional parent of <emphasis
+	  role="italic">ptr</emphasis>.
+        </para>
+        <para>
+	  The return value of talloc_reference() is always the original
+	  pointer <emphasis role="italic">ptr</emphasis>, unless talloc ran
+	  out of memory in creating the reference in which case it will
+	  return NULL (each additional reference consumes around 48 bytes
+	  of memory on intel x86 platforms).
+        </para>
+        <para>
+	  If <emphasis role="italic">ptr</emphasis> is NULL, then the
+	  function is a no-op, and simply returns NULL.
+        </para>
+        <para>
+	  After creating a reference you can free it in one of the
+	  following ways:

+        <itemizedlist>
+          <listitem>
+            <para>
+	      you can talloc_free() any parent of the original pointer. 
+	      That will reduce the number of parents of this pointer by 1,
+	      and will cause this pointer to be freed if it runs out of
+	      parents.
+            </para>
+          </listitem>
+          <listitem>
+            <para>
+	      you can talloc_free() the pointer itself.  That will destroy
+	      the most recently established parent to the pointer and leave
+	      the pointer as a child of its current parent.
+            </para>
+          </listitem>
+        </itemizedlist>
+      </para>
+      <para>
+	For more control on which parent to remove, see <link
+	linkend="talloc_unlink"><quote>talloc_unlink()</quote></link>.
+      </para>
+    </refsect2>
+    <refsect2 id="talloc_unlink"><title>int talloc_unlink(const void *ctx, const void *ptr);</title>
+        <para>
+	  The talloc_unlink() function removes a specific parent from
+	  <emphasis role="italic">ptr</emphasis>. The <emphasis
+	  role="italic">ctx</emphasis> passed must either be a context used
+	  in talloc_reference() with this pointer, or must be a direct
+	  parent of ptr.
+        </para>
+        <para>
+	  Note that if the parent has already been removed using
+	  talloc_free() then this function will fail and will return -1. 
+	  Likewise, if <emphasis role="italic">ptr</emphasis> is NULL, then
+	  the function will make no modifications and return -1.
+        </para>
+        <para>
+	  Usually you can just use talloc_free() instead of
+	  talloc_unlink(), but sometimes it is useful to have the
+	  additional control on which parent is removed.
+        </para>
+    </refsect2>
+    <refsect2 id="talloc_set_destructor"><title>void talloc_set_destructor(const void *ptr, int (*destructor)(void *));</title>
+        <para>
+	  The function talloc_set_destructor() sets the <emphasis
+	  role="italic">destructor</emphasis> for the pointer <emphasis
+	  role="italic">ptr</emphasis>.  A <emphasis
+	  role="italic">destructor</emphasis> is a function that is called
+	  when the memory used by a pointer is about to be released.  The
+	  destructor receives <emphasis role="italic">ptr</emphasis> as an
+	  argument, and should return 0 for success and -1 for failure.
+        </para>
+        <para>
+	  The <emphasis role="italic">destructor</emphasis> can do anything
+	  it wants to, including freeing other pieces of memory.  A common
+	  use for destructors is to clean up operating system resources
+	  (such as open file descriptors) contained in the structure the
+	  destructor is placed on.
+        </para>
+        <para>
+	  You can only place one destructor on a pointer.  If you need more
+	  than one destructor then you can create a zero-length child of
+	  the pointer and place an additional destructor on that.
+        </para>
+        <para>
+	  To remove a destructor call talloc_set_destructor() with NULL for
+	  the destructor.
+        </para>
+        <para>
+	  If your destructor attempts to talloc_free() the pointer that it
+	  is the destructor for then talloc_free() will return -1 and the
+	  free will be ignored.  This would be a pointless operation
+	  anyway, as the destructor is only called when the memory is just
+	  about to go away.

+    <refsect2><title>int talloc_increase_ref_count(const void *<emphasis role="italic">ptr</emphasis>);</title>
+        <para>
+	  The talloc_increase_ref_count(<emphasis

+        </para>
+        <programlisting>talloc_reference(NULL, ptr);</programlisting>
+        <para>
+	  You can use either syntax, depending on which you think is

+	  Each talloc pointer has a "name".  The name is used principally

+        </para>
+        <para>

+      All the additional features of talloc(3) over malloc(3) do come at a
+      price.  We have a simple performance test in Samba4 that measures
+      talloc() versus malloc() performance, and it seems that talloc() is
+      about 10% slower than malloc() on my x86 Debian Linux box.  For
+      Samba, the great reduction in code complexity that we get by using
+      talloc makes this worthwhile, especially as the total overhead of
+      talloc/malloc in Samba is already quite small.

+Using talloc in Samba4
+----------------------
+
+Andrew Tridgell
+September 2004
+
+The most current version of this document is available at
+   http://samba.org/ftp/unpacked/samba4/source/lib/talloc/talloc_guide.txt
+
+If you are used to the "old" talloc from Samba3 before 3.0.20 then please read
+this carefully, as talloc has changed a lot. With 3.0.20 (or 3.0.14?) the
+Samba4 talloc has been ported back to Samba3, so this guide applies to both.
+
+The new talloc is a hierarchical, reference counted memory pool system
+with destructors. Quite a mouthful really, but not too bad once you
+get used to it.
+
+Perhaps the biggest change from Samba3 is that there is no distinction
+between a "talloc context" and a "talloc pointer". Any pointer
+returned from talloc() is itself a valid talloc context. This means
+you can do this:
+
+  struct foo *X = talloc(mem_ctx, struct foo);
+  X->name = talloc_strdup(X, "foo");
+
+and the pointer X->name would be a "child" of the talloc context "X"
+which is itself a child of mem_ctx. So if you do talloc_free(mem_ctx)
+then it is all destroyed, whereas if you do talloc_free(X) then just X
+and X->name are destroyed, and if you do talloc_free(X->name) then
+just the name element of X is destroyed.
+
+If you think about this, then what this effectively gives you is an
+n-ary tree, where you can free any part of the tree with
+talloc_free().
+
+If you find this confusing, then I suggest you run the testsuite to
+watch talloc in action. You may also like to add your own tests to
+testsuite.c to clarify how some particular situation is handled.
+
+
+Performance
+-----------
+
+All the additional features of talloc() over malloc() do come at a
+price. We have a simple performance test in Samba4 that measures
+talloc() versus malloc() performance, and it seems that talloc() is
+about 4% slower than malloc() on my x86 Debian Linux box. For Samba,
+the great reduction in code complexity that we get by using talloc
+makes this worthwhile, especially as the total overhead of
+talloc/malloc in Samba is already quite small.
+
+
+talloc API
+----------
+
+The following is a complete guide to the talloc API. Read it all at
+least twice.
+
+Multi-threading
+---------------
+
+talloc itself does not deal with threads. It is thread-safe (assuming  
+the underlying "malloc" is), as long as each thread uses different  
+memory contexts.
+If two threads uses the same context then they need to synchronize in  
+order to be safe. In particular:
+- when using talloc_enable_leak_report(), giving directly NULL as a  
+parent context implicitly refers to a hidden "null context" global  
+variable, so this should not be used in a multi-threaded environment  
+without proper synchronization ;
+- the context returned by talloc_autofree_context() is also global so  
+shouldn't be used by several threads simultaneously without  
+synchronization.

+(type *)talloc(const void *context, type);
+
+The talloc() macro is the core of the talloc library. It takes a
+memory context and a type, and returns a pointer to a new area of
+memory of the given type.
+
+The returned pointer is itself a talloc context, so you can use it as
+the context argument to more calls to talloc if you wish.
+
+The returned pointer is a "child" of the supplied context. This means
+that if you talloc_free() the context then the new child disappears as
+well. Alternatively you can free just the child.
+
+The context argument to talloc() can be NULL, in which case a new top
+level context is created. 
+
+
+=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
+void *talloc_size(const void *context, size_t size);
+
+The function talloc_size() should be used when you don't have a
+convenient type to pass to talloc(). Unlike talloc(), it is not type
+safe (as it returns a void *), so you are on your own for type checking.
+
+=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
+(typeof(ptr)) talloc_ptrtype(const void *ctx, ptr);
+
+The talloc_ptrtype() macro should be used when you have a pointer and
+want to allocate memory to point at with this pointer. When compiling
+with gcc >= 3 it is typesafe. Note this is a wrapper of talloc_size()
+and talloc_get_name() will return the current location in the source file.
+and not the type.
+
+=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
+int talloc_free(void *ptr);
+
+The talloc_free() function frees a piece of talloc memory, and all its
+children. You can call talloc_free() on any pointer returned by
+talloc().
+
+The return value of talloc_free() indicates success or failure, with 0
+returned for success and -1 for failure. The only possible failure
+condition is if the pointer had a destructor attached to it and the
+destructor returned -1. See talloc_set_destructor() for details on
+destructors.
+
+If this pointer has an additional parent when talloc_free() is called
+then the memory is not actually released, but instead the most
+recently established parent is destroyed. See talloc_reference() for
+details on establishing additional parents.
+
+For more control on which parent is removed, see talloc_unlink()
+
+talloc_free() operates recursively on its children.
+
+
+=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
+int talloc_free_children(void *ptr);
+
+The talloc_free_children() walks along the list of all children of a
+talloc context and talloc_free()s only the children, not the context
+itself.
+
+
+=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
+void *talloc_reference(const void *context, const void *ptr);
+
+The talloc_reference() function makes "context" an additional parent
+of "ptr".
+
+The return value of talloc_reference() is always the original pointer
+"ptr", unless talloc ran out of memory in creating the reference in
+which case it will return NULL (each additional reference consumes
+around 48 bytes of memory on intel x86 platforms).
+
+If "ptr" is NULL, then the function is a no-op, and simply returns NULL.
+
+After creating a reference you can free it in one of the following
+ways:
+
+  - you can talloc_free() any parent of the original pointer. That
+    will reduce the number of parents of this pointer by 1, and will
+    cause this pointer to be freed if it runs out of parents.
+
+  - you can talloc_free() the pointer itself. That will destroy the
+    most recently established parent to the pointer and leave the
+    pointer as a child of its current parent.
+
+For more control on which parent to remove, see talloc_unlink()
+
+
+=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
+int talloc_unlink(const void *context, const void *ptr);
+
+The talloc_unlink() function removes a specific parent from ptr. The
+context passed must either be a context used in talloc_reference()
+with this pointer, or must be a direct parent of ptr. 
+
+Note that if the parent has already been removed using talloc_free()
+then this function will fail and will return -1.  Likewise, if "ptr"
+is NULL, then the function will make no modifications and return -1.
+
+Usually you can just use talloc_free() instead of talloc_unlink(), but
+sometimes it is useful to have the additional control on which parent
+is removed.
+
+
+=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
+void talloc_set_destructor(const void *ptr, int (*destructor)(void *));
+
+The function talloc_set_destructor() sets the "destructor" for the
+pointer "ptr". A destructor is a function that is called when the
+memory used by a pointer is about to be released. The destructor
+receives the pointer as an argument, and should return 0 for success
+and -1 for failure.
+
+The destructor can do anything it wants to, including freeing other
+pieces of memory. A common use for destructors is to clean up
+operating system resources (such as open file descriptors) contained
+in the structure the destructor is placed on.
+
+You can only place one destructor on a pointer. If you need more than
+one destructor then you can create a zero-length child of the pointer
+and place an additional destructor on that.
+
+To remove a destructor call talloc_set_destructor() with NULL for the
+destructor.
+
+If your destructor attempts to talloc_free() the pointer that it is
+the destructor for then talloc_free() will return -1 and the free will
+be ignored. This would be a pointless operation anyway, as the
+destructor is only called when the memory is just about to go away.
+
+
+=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
+int talloc_increase_ref_count(const void *ptr);
+
+The talloc_increase_ref_count(ptr) function is exactly equivalent to:
+
+  talloc_reference(NULL, ptr);
+
+You can use either syntax, depending on which you think is clearer in
+your code.
+
+It returns 0 on success and -1 on failure.
+
+=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
+size_t talloc_reference_count(const void *ptr);
+
+Return the number of references to the pointer.
+
+=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
+void talloc_set_name(const void *ptr, const char *fmt, ...);
+
+Each talloc pointer has a "name". The name is used principally for
+debugging purposes, although it is also possible to set and get the
+name on a pointer in as a way of "marking" pointers in your code.
+
+The main use for names on pointer is for "talloc reports". See
+talloc_report() and talloc_report_full() for details. Also see
+talloc_enable_leak_report() and talloc_enable_leak_report_full().
+
+The talloc_set_name() function allocates memory as a child of the
+pointer. It is logically equivalent to:
+  talloc_set_name_const(ptr, talloc_asprintf(ptr, fmt, ...));
+
+Note that multiple calls to talloc_set_name() will allocate more
+memory without releasing the name. All of the memory is released when
+the ptr is freed using talloc_free().
+
+
+=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
+void talloc_set_name_const(const void *ptr, const char *name);
+
+The function talloc_set_name_const() is just like talloc_set_name(),
+but it takes a string constant, and is much faster. It is extensively
+used by the "auto naming" macros, such as talloc_p().
+
+This function does not allocate any memory. It just copies the
+supplied pointer into the internal representation of the talloc
+ptr. This means you must not pass a name pointer to memory that will
+disappear before the ptr is freed with talloc_free().
+
+
+=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
+void *talloc_named(const void *context, size_t size, const char *fmt, ...);
+
+The talloc_named() function creates a named talloc pointer. It is
+equivalent to:
+
+   ptr = talloc_size(context, size);
+   talloc_set_name(ptr, fmt, ....);
+
+
+=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
+void *talloc_named_const(const void *context, size_t size, const char *name);
+
+This is equivalent to:
+
+   ptr = talloc_size(context, size);
+   talloc_set_name_const(ptr, name);
+
+
+=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
+const char *talloc_get_name(const void *ptr);
+
+This returns the current name for the given talloc pointer. See
+talloc_set_name() for details.
+
+
+=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
+void *talloc_init(const char *fmt, ...);
+
+This function creates a zero length named talloc context as a top
+level context. It is equivalent to:
+
+  talloc_named(NULL, 0, fmt, ...);
+
+
+=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
+void *talloc_new(void *ctx);
+
+This is a utility macro that creates a new memory context hanging
+off an exiting context, automatically naming it "talloc_new: __location__"
+where __location__ is the source line it is called from. It is
+particularly useful for creating a new temporary working context.
+
+
+=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
+(type *)talloc_realloc(const void *context, void *ptr, type, count);
+
+The talloc_realloc() macro changes the size of a talloc
+pointer. The "count" argument is the number of elements of type "type"
+that you want the resulting pointer to hold. 
+
+talloc_realloc() has the following equivalences:
+
+  talloc_realloc(context, NULL, type, 1) ==> talloc(context, type);
+  talloc_realloc(context, NULL, type, N) ==> talloc_array(context, type, N);
+  talloc_realloc(context, ptr, type, 0)  ==> talloc_free(ptr);
+
+The "context" argument is only used if "ptr" is NULL, otherwise it is
+ignored.
+
+talloc_realloc() returns the new pointer, or NULL on failure. The call
+will fail either due to a lack of memory, or because the pointer has
+more than one parent (see talloc_reference()).
+
+
+=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
+void *talloc_realloc_size(const void *context, void *ptr, size_t size);
+
+the talloc_realloc_size() function is useful when the type is not 
+known so the typesafe talloc_realloc() cannot be used.
+
+
+=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
+void *talloc_steal(const void *new_ctx, const void *ptr);
+
+The talloc_steal() function changes the parent context of a talloc
+pointer. It is typically used when the context that the pointer is
+currently a child of is going to be freed and you wish to keep the
+memory for a longer time. 
+
+The talloc_steal() function returns the pointer that you pass it. It
+does not have any failure modes.
+
+NOTE: It is possible to produce loops in the parent/child relationship
+if you are not careful with talloc_steal(). No guarantees are provided
+as to your sanity or the safety of your data if you do this.
+
+talloc_steal (new_ctx, NULL) will return NULL with no sideeffects.
+
+=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
+size_t talloc_total_size(const void *ptr);
+
+The talloc_total_size() function returns the total size in bytes used
+by this pointer and all child pointers. Mostly useful for debugging.
+
+Passing NULL is allowed, but it will only give a meaningful result if
+talloc_enable_leak_report() or talloc_enable_leak_report_full() has
+been called.
+
+
+=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
+size_t talloc_total_blocks(const void *ptr);
+
+The talloc_total_blocks() function returns the total memory block
+count used by this pointer and all child pointers. Mostly useful for
+debugging.
+
+Passing NULL is allowed, but it will only give a meaningful result if
+talloc_enable_leak_report() or talloc_enable_leak_report_full() has
+been called.
+
+=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
+void talloc_report_depth_cb(const void *ptr, int depth, int max_depth,

+			    		     int depth, int max_depth,
+					     int is_ref,
+					     void *priv),
+			    void *priv);
+
+This provides a more flexible reports than talloc_report(). It
+will recursively call the callback for the entire tree of memory
+referenced by the pointer. References in the tree are passed with
+is_ref = 1 and the pointer that is referenced.
+
+You can pass NULL for the pointer, in which case a report is
+printed for the top level memory context, but only if
+talloc_enable_leak_report() or talloc_enable_leak_report_full()
+has been called.
+
+The recursion is stopped when depth >= max_depth.
+max_depth = -1 means only stop at leaf nodes.

+
+=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
+void talloc_report_depth_file(const void *ptr, int depth, int max_depth, FILE *f);
+
+This provides a more flexible reports than talloc_report(). It

+
+
+=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
+void talloc_report(const void *ptr, FILE *f);
+
+The talloc_report() function prints a summary report of all memory
+used by ptr. One line of report is printed for each immediate child of
+ptr, showing the total memory and number of blocks used by that child.
+
+You can pass NULL for the pointer, in which case a report is printed
+for the top level memory context, but only if
+talloc_enable_leak_report() or talloc_enable_leak_report_full() has
+been called.
+
+
+=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
+void talloc_report_full(const void *ptr, FILE *f);
+
+This provides a more detailed report than talloc_report(). It will
+recursively print the ensire tree of memory referenced by the
+pointer. References in the tree are shown by giving the name of the
+pointer that is referenced.
+
+You can pass NULL for the pointer, in which case a report is printed
+for the top level memory context, but only if
+talloc_enable_leak_report() or talloc_enable_leak_report_full() has
+been called.
+
+
+=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
+void talloc_enable_leak_report(void);
+
+This enables calling of talloc_report(NULL, stderr) when the program
+exits. In Samba4 this is enabled by using the --leak-report command
+line option.
+
+For it to be useful, this function must be called before any other
+talloc function as it establishes a "null context" that acts as the
+top of the tree. If you don't call this function first then passing
+NULL to talloc_report() or talloc_report_full() won't give you the
+full tree printout.
+
+Here is a typical talloc report:
+

+void talloc_enable_leak_report_full(void);
+
+This enables calling of talloc_report_full(NULL, stderr) when the
+program exits. In Samba4 this is enabled by using the
+--leak-report-full command line option.
+
+For it to be useful, this function must be called before any other
+talloc function as it establishes a "null context" that acts as the
+top of the tree. If you don't call this function first then passing
+NULL to talloc_report() or talloc_report_full() won't give you the

+
+This is a non-macro version of talloc_realloc(), which is useful

+<h1>talloc</h1>
+
+talloc is a hierarchical pool based memory allocator with
+destructors. It is the core memory allocator used in Samba4, and has
+made a huge difference in many aspects of Samba4 development.<p>
+
+To get started with talloc, I would recommend you read the <a
+href="http://samba.org/ftp/unpacked/talloc/talloc_guide.txt">talloc guide</a>.
+
+<h2>Discussion and bug reports</h2>
+
+talloc does not currently have its own mailing list or bug tracking
+system. For now, please use the <a
+href="https://lists.samba.org/mailman/listinfo/samba-technical">samba-technical</a>
+mailing list, and the <a href="http://bugzilla.samba.org/">Samba
+bugzilla</a> bug tracking system.
+
+<h2>Download</h2>
+
+You can download the latest release either via rsync or git.<br>
+<br>
+To fetch via git see the following guide:<br>
+<a href="http://wiki.samba.org/index.php/Using_Git_for_Samba_Development">Using Git for Samba Development</a><br>
+Once you have cloned the tree switch to the v4-0-test branch and cd into the source/lib/talloc directory.<br>
+<br>
+To fetch via rsync use this command:
+
+<pre>
+  rsync -Pavz samba.org::ftp/unpacked/talloc .

+  transaction design:
+
+  - only allow a single transaction at a time per database. This makes
+    using the transaction API simpler, as otherwise the caller would
+    have to cope with temporary failures in transactions that conflict
+    with other current transactions
+
+  - keep the transaction recovery information in the same file as the
+    database, using a special 'transaction recovery' record pointed at
+    by the header. This removes the need for extra journal files as
+    used by some other databases
+
+  - dynamically allocated the transaction recover record, re-using it
+    for subsequent transactions. If a larger record is needed then
+    tdb_free() the old record to place it on the normal tdb freelist
+    before allocating the new record
+
+  - during transactions, keep a linked list of writes all that have
+    been performed by intercepting all tdb_write() calls. The hooked
+    transaction versions of tdb_read() and tdb_write() check this
+    linked list and try to use the elements of the list in preference
+    to the real database.
+
+  - don't allow any locks to be held when a transaction starts,
+    otherwise we can end up with deadlock (plus lack of lock nesting
+    in posix locks would mean the lock is lost)
+
+  - if the caller gains a lock during the transaction but doesn't
+    release it then fail the commit
+
+  - allow for nested calls to tdb_transaction_start(), re-using the
+    existing transaction record. If the inner transaction is cancelled
+    then a subsequent commit will fail
+ 
+  - keep a mirrored copy of the tdb hash chain heads to allow for the
+    fast hash heads scan on traverse, updating the mirrored copy in
+    the transaction version of tdb_write
+
+  - allow callers to mix transaction and non-transaction use of tdb,
+    although once a transaction is started then an exclusive lock is
+    gained until the transaction is committed or cancelled
+
+  - the commit stategy involves first saving away all modified data
+    into a linearised buffer in the transaction recovery area, then
+    marking the transaction recovery area with a magic value to
+    indicate a valid recovery record. In total 4 fsync/msync calls are
+    needed per commit to prevent race conditions. It might be possible
+    to reduce this to 3 or even 2 with some more work.
+
+  - check for a valid recovery record on open of the tdb, while the
+    global lock is held. Automatically recover from the transaction
+    recovery area if needed, then continue with the open as
+    usual. This allows for smooth crash recovery with no administrator
+    intervention.
+
+  - if TDB_NOSYNC is passed to flags in tdb_open then transactions are
+    still available, but no transaction recovery area is used and no
+    fsync/msync calls are made.

+tdb - a trivial database system
+tridge@linuxcare.com December 1999
+==================================
+
+This is a simple database API. It was inspired by the realisation that
+in Samba we have several ad-hoc bits of code that essentially
+implement small databases for sharing structures between parts of
+Samba. As I was about to add another I realised that a generic
+database module was called for to replace all the ad-hoc bits.
+
+I based the interface on gdbm. I couldn't use gdbm as we need to be
+able to have multiple writers to the databases at one time.
+
+Compilation
+-----------
+
+add HAVE_MMAP=1 to use mmap instead of read/write
+add NOLOCK=1 to disable locking code
+
+Testing
+-------
+
+Compile tdbtest.c and link with gdbm for testing. tdbtest will perform
+identical operations via tdb and gdbm then make sure the result is the
+same
+
+Also included is tdbtool, which allows simple database manipulation
+on the commandline.
+
+tdbtest and tdbtool are not built as part of Samba, but are included
+for completeness.
+
+Interface
+---------
+
+The interface is very similar to gdbm except for the following:
+
+- different open interface. The tdb_open call is more similar to a
+  traditional open()
+- no tdbm_reorganise() function
+- no tdbm_sync() function. No operations are cached in the library anyway
+- added a tdb_traverse() function for traversing the whole database
+- added transactions support
+
+A general rule for using tdb is that the caller frees any returned
+TDB_DATA structures. Just call free(p.dptr) to free a TDB_DATA
+return value called p. This is the same as gdbm.
+
+here is a full list of tdb functions with brief descriptions.
+
+
+----------------------------------------------------------------------
+TDB_CONTEXT *tdb_open(char *name, int hash_size, int tdb_flags,
+		      int open_flags, mode_t mode)
+
+   open the database, creating it if necessary 
+
+   The open_flags and mode are passed straight to the open call on the database
+   file. A flags value of O_WRONLY is invalid
+
+   The hash size is advisory, use zero for a default value. 
+
+   return is NULL on error
+
+   possible tdb_flags are:
+    TDB_CLEAR_IF_FIRST - clear database if we are the only one with it open
+    TDB_INTERNAL - don't use a file, instaed store the data in
+                   memory. The filename is ignored in this case.
+    TDB_NOLOCK - don't do any locking
+    TDB_NOMMAP - don't use mmap
+    TDB_NOSYNC - don't synchronise transactions to disk
+
+----------------------------------------------------------------------
+TDB_CONTEXT *tdb_open_ex(char *name, int hash_size, int tdb_flags,
+		         int open_flags, mode_t mode,
+			 tdb_log_func log_fn,
+			 tdb_hash_func hash_fn)
+
+This is like tdb_open(), but allows you to pass an initial logging and
+hash function. Be careful when passing a hash function - all users of
+the database must use the same hash function or you will get data
+corruption.
+
+
+----------------------------------------------------------------------
+char *tdb_error(TDB_CONTEXT *tdb);
+
+     return a error string for the last tdb error
+
+----------------------------------------------------------------------
+int tdb_close(TDB_CONTEXT *tdb);
+
+   close a database
+
+----------------------------------------------------------------------
+int tdb_update(TDB_CONTEXT *tdb, TDB_DATA key, TDB_DATA dbuf);
+
+   update an entry in place - this only works if the new data size
+   is <= the old data size and the key exists.
+   on failure return -1
+
+----------------------------------------------------------------------
+TDB_DATA tdb_fetch(TDB_CONTEXT *tdb, TDB_DATA key);
+
+   fetch an entry in the database given a key 
+   if the return value has a null dptr then a error occurred
+
+   caller must free the resulting data
+
+----------------------------------------------------------------------
+int tdb_exists(TDB_CONTEXT *tdb, TDB_DATA key);
+
+   check if an entry in the database exists 
+
+   note that 1 is returned if the key is found and 0 is returned if not found
+   this doesn't match the conventions in the rest of this module, but is
+   compatible with gdbm
+
+----------------------------------------------------------------------
+int tdb_traverse(TDB_CONTEXT *tdb, int (*fn)(TDB_CONTEXT *tdb,
+                 TDB_DATA key, TDB_DATA dbuf, void *state), void *state);
+
+   traverse the entire database - calling fn(tdb, key, data, state) on each 
+   element.
+
+   return -1 on error or the record count traversed
+
+   if fn is NULL then it is not called
+
+   a non-zero return value from fn() indicates that the traversal
+   should stop. Traversal callbacks may not start transactions.
+
+   WARNING: The data buffer given to the callback fn does NOT meet the
+   alignment restrictions malloc gives you.
+
+----------------------------------------------------------------------
+int tdb_traverse_read(TDB_CONTEXT *tdb, int (*fn)(TDB_CONTEXT *tdb,
+                     TDB_DATA key, TDB_DATA dbuf, void *state), void *state);
+
+   traverse the entire database - calling fn(tdb, key, data, state) on
+   each element, but marking the database read only during the
+   traversal, so any write operations will fail. This allows tdb to
+   use read locks, which increases the parallelism possible during the
+   traversal.
+
+   return -1 on error or the record count traversed
+
+   if fn is NULL then it is not called
+
+   a non-zero return value from fn() indicates that the traversal
+   should stop. Traversal callbacks may not start transactions.
+
+----------------------------------------------------------------------
+TDB_DATA tdb_firstkey(TDB_CONTEXT *tdb);
+
+   find the first entry in the database and return its key
+
+   the caller must free the returned data
+
+----------------------------------------------------------------------
+TDB_DATA tdb_nextkey(TDB_CONTEXT *tdb, TDB_DATA key);
+
+   find the next entry in the database, returning its key
+
+   the caller must free the returned data
+
+----------------------------------------------------------------------
+int tdb_delete(TDB_CONTEXT *tdb, TDB_DATA key);
+
+   delete an entry in the database given a key
+
+----------------------------------------------------------------------
+int tdb_store(TDB_CONTEXT *tdb, TDB_DATA key, TDB_DATA dbuf, int flag);
+
+   store an element in the database, replacing any existing element
+   with the same key 
+
+   If flag==TDB_INSERT then don't overwrite an existing entry
+   If flag==TDB_MODIFY then don't create a new entry
+
+   return 0 on success, -1 on failure
+
+----------------------------------------------------------------------
+int tdb_writelock(TDB_CONTEXT *tdb);
+
+   lock the database. If we already have it locked then don't do anything
+
+----------------------------------------------------------------------
+int tdb_writeunlock(TDB_CONTEXT *tdb);
+   unlock the database
+
+----------------------------------------------------------------------
+int tdb_lockchain(TDB_CONTEXT *tdb, TDB_DATA key);
+
+   lock one hash chain. This is meant to be used to reduce locking
+   contention - it cannot guarantee how many records will be locked
+
+----------------------------------------------------------------------
+int tdb_unlockchain(TDB_CONTEXT *tdb, TDB_DATA key);
+
+   unlock one hash chain
+
+----------------------------------------------------------------------
+int tdb_transaction_start(TDB_CONTEXT *tdb)
+
+   start a transaction. All operations after the transaction start can
+   either be committed with tdb_transaction_commit() or cancelled with
+   tdb_transaction_cancel(). 
+
+   If you call tdb_transaction_start() again on the same tdb context
+   while a transaction is in progress, then the same transaction
+   buffer is re-used. The number of tdb_transaction_{commit,cancel}
+   operations must match the number of successful
+   tdb_transaction_start() calls.
+
+   Note that transactions are by default disk synchronous, and use a
+   recover area in the database to automatically recover the database
+   on the next open if the system crashes during a transaction. You
+   can disable the synchronous transaction recovery setup using the
+   TDB_NOSYNC flag, which will greatly speed up operations at the risk
+   of corrupting your database if the system crashes.
+
+   Operations made within a transaction are not visible to other users
+   of the database until a successful commit.
+
+----------------------------------------------------------------------
+int tdb_transaction_cancel(TDB_CONTEXT *tdb)
+
+   cancel a current transaction, discarding all write and lock
+   operations that have been made since the transaction started.
+
+
+----------------------------------------------------------------------
+int tdb_transaction_commit(TDB_CONTEXT *tdb)
+
+   commit a current transaction, updating the database and releasing
+   the transaction locks.

+   Flags/methods for returning states.
+   
+   The swig conversion methods, as ConvertPtr, return and integer 
+   that tells if the conversion was successful or not. And if not,
+   an error code can be returned (see swigerrors.swg for the codes).
+   
+   Use the following macros/flags to set or process the returning
+   states.
+   
+   In old swig versions, you usually write code as:
+
+     if (SWIG_ConvertPtr(obj,vptr,ty.flags) != -1) {
+       // success code
+     } else {
+       //fail code
+     }
+
+   Now you can be more explicit as:
+
+    int res = SWIG_ConvertPtr(obj,vptr,ty.flags);
+    if (SWIG_IsOK(res)) {
+      // success code
+    } else {
+      // fail code
+    }
+
+   that seems to be the same, but now you can also do
+
+    Type *ptr;
+    int res = SWIG_ConvertPtr(obj,(void **)(&ptr),ty.flags);
+    if (SWIG_IsOK(res)) {
+      // success code
+      if (SWIG_IsNewObj(res) {
+        ...
+	delete *ptr;
+      } else {
+        ...
+      }
+    } else {
+      // fail code
+    }
+    
+   I.e., now SWIG_ConvertPtr can return new objects and you can
+   identify the case and take care of the deallocation. Of course that
+   requires also to SWIG_ConvertPtr to return new result values, as
+
+      int SWIG_ConvertPtr(obj, ptr,...) {         
+        if (<obj is ok>) {			       
+          if (<need new object>) {		       
+            *ptr = <ptr to new allocated object>; 
+            return SWIG_NEWOBJ;		       
+          } else {				       
+            *ptr = <ptr to old object>;	       
+            return SWIG_OLDOBJ;		       
+          } 				       
+        } else {				       
+          return SWIG_BADOBJ;		       
+        }					       
+      }
+
+   Of course, returning the plain '0(success)/-1(fail)' still works, but you can be
+   more explicit by returning SWIG_BADOBJ, SWIG_ERROR or any of the
+   swig errors code.
+
+   Finally, if the SWIG_CASTRANK_MODE is enabled, the result code
+   allows to return the 'cast rank', for example, if you have this
+
+       int food(double)
+       int fooi(int);
+
+   and you call
+ 
+      food(1)   // cast rank '1'  (1 -> 1.0)
+      fooi(1)   // cast rank '0'
+
+   just use the SWIG_AddCast()/SWIG_CheckState()

+ * Type initialization:
+ * This problem is tough by the requirement that no dynamic 
+ * memory is used. Also, since swig_type_info structures store pointers to 
+ * swig_cast_info structures and swig_cast_info structures store pointers back
+ * to swig_type_info structures, we need some lookup code at initialization. 
+ * The idea is that swig generates all the structures that are needed. 
+ * The runtime then collects these partially filled structures. 
+ * The SWIG_InitializeModule function takes these initial arrays out of 
+ * swig_module, and does all the lookup, filling in the swig_module.types
+ * array with the correct data and linking the correct swig_cast_info
+ * structures together.
+ *
+ * The generated swig_type_info structures are assigned staticly to an initial 
+ * array. We just loop through that array, and handle each type individually.
+ * First we lookup if this type has been already loaded, and if so, use the
+ * loaded structure instead of the generated one. Then we have to fill in the
+ * cast linked list. The cast data is initially stored in something like a
+ * two-dimensional array. Each row corresponds to a type (there are the same
+ * number of rows as there are in the swig_type_initial array). Each entry in
+ * a column is one of the swig_cast_info structures for that type.
+ * The cast_initial array is actually an array of arrays, because each row has
+ * a variable number of columns. So to actually build the cast linked list,
+ * we find the array of casts associated with the type, and loop through it 
+ * adding the casts to the list. The one last trick we need to do is making
+ * sure the type pointer in the swig_cast_info struct is correct.
+ *
+ * First off, we lookup the cast->type name to see if it is already loaded. 
+ * There are three cases to handle:
+ *  1) If the cast->type has already been loaded AND the type we are adding
+ *     casting info to has not been loaded (it is in this module), THEN we
+ *     replace the cast->type pointer with the type pointer that has already
+ *     been loaded.
+ *  2) If BOTH types (the one we are adding casting info to, and the 
+ *     cast->type) are loaded, THEN the cast info has already been loaded by
+ *     the previous module so we just ignore it.
+ *  3) Finally, if cast->type has not already been loaded, then we add that
+ *     swig_cast_info to the linked list (because the cast->type) pointer will
+ *     be correct.

+/*
+
+  This program is meant for backup/restore of tdb databases. Typical usage would be:
+     tdbbackup *.tdb
+  when Samba shuts down cleanly, which will make a backup of all the local databases
+  to *.bak files. Then on Samba startup you would use:
+     tdbbackup -v *.tdb
+  and this will check the databases for corruption and if corruption is detected then
+  the backup will be restored.
+
+  You may also like to do a backup on a regular basis while Samba is
+  running, perhaps using cron.
+
+  The reason this program is needed is to cope with power failures
+  while Samba is running. A power failure could lead to database
+  corruption and Samba will then not start correctly.
+
+  Note that many of the databases in Samba are transient and thus
+  don't need to be backed up, so you can optimise the above a little
+  by only running the backup on the critical databases.

+<h1>tdb</h1>
+
+TDB is a Trivial Database. In concept, it is very much like GDBM, and BSD's DB 
+except that it allows multiple simultaneous writers and uses locking 
+internally to keep writers from trampling on each other. TDB is also extremely 
+small.
+
+<h2>Discussion and bug reports</h2>
+
+tdb does not currently have its own mailing list or bug tracking
+system. For now, please use the <a
+href="https://lists.samba.org/mailman/listinfo/samba-technical">samba-technical</a>
+mailing list, and the <a href="http://bugzilla.samba.org/">Samba
+bugzilla</a> bug tracking system.
+
+<h2>Download</h2>
+
+You can download the latest release either via rsync or git.<br>
+<br>
+To fetch via git see the following guide:<br>
+<a href="http://wiki.samba.org/index.php/Using_Git_for_Samba_Development">Using Git for Samba Development</a><br>
+Once you have cloned the tree switch to the v4-0-test branch and cd into the source/lib/tdb directory.<br>
+<br>
+To fetch via rsync use these commands:
+
+<pre>
+  rsync -Pavz samba.org::ftp/unpacked/tdb .
+  rsync -Pavz samba.org::ftp/unpacked/libreplace .
+</pre>
+
+and build in tdb. It will find the replace library in the directory
+above automatically.
