+ <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:
+ </para>
+ <para>
+ <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.
+ </para>
+ </refsect2>
+ <refsect2><title>int talloc_increase_ref_count(const void *<emphasis role="italic">ptr</emphasis>);</title>
+ <para>
+ The talloc_increase_ref_count(<emphasis
+ role="italic">ptr</emphasis>) function is exactly equivalent to:
+ </para>
+ <programlisting>talloc_reference(NULL, ptr);</programlisting>
+ <para>
+ You can use either syntax, depending on which you think is
+ clearer in your code.
+ </para>
+ <para>
+ It returns 0 on success and -1 on failure.
+ </para>
+ </refsect2>
+ <refsect2><title>size_t talloc_reference_count(const void *<emphasis role="italic">ptr</emphasis>);</title>
+ <para>
+ Return the number of references to the pointer.
+ </para>
+ </refsect2>
+ <refsect2 id="talloc_set_name"><title>void talloc_set_name(const void *ptr, const char *fmt, ...);</title>
+ <para>
+ 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.
+ </para>
+ <para>
+ The main use for names on pointer is for "talloc reports". See
+ <link
+ linkend="talloc_report"><quote>talloc_report_depth_cb()</quote></link>,
+ <link
+ linkend="talloc_report"><quote>talloc_report_depth_file()</quote></link>,
+ <link

+ and <link
+ linkend="talloc_enable_leak_report_full"><quote>talloc_enable_leak_report_full()</quote></link>.
+ </para>
+ <para>
+ The talloc_set_name() function allocates memory as a child of the
+ pointer. It is logically equivalent to:
+ </para>
+ <programlisting>talloc_set_name_const(ptr, talloc_asprintf(ptr, fmt, ...));</programlisting>
+ <para>
+ 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().
+ </para>
+ </refsect2>
+ <refsect2><title>void talloc_set_name_const(const void *<emphasis role="italic">ptr</emphasis>, const char *<emphasis role="italic">name</emphasis>);</title>
+ <para>
+ 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().
+ </para>
+ <para>
+ 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 <emphasis
+ role="italic">name</emphasis> pointer to memory that will
+ disappear before <emphasis role="italic">ptr</emphasis> is freed
+ with talloc_free().
+ </para>
+ </refsect2>
+ <refsect2><title>void *talloc_named(const void *<emphasis role="italic">ctx</emphasis>, size_t <emphasis role="italic">size</emphasis>, const char *<emphasis role="italic">fmt</emphasis>, ...);</title>
+ <para>
+ The talloc_named() function creates a named talloc pointer. It
+ is equivalent to:
+ </para>
+ <programlisting>ptr = talloc_size(ctx, size);
+talloc_set_name(ptr, fmt, ....);</programlisting>
+ </refsect2>
+ <refsect2><title>void *talloc_named_const(const void *<emphasis role="italic">ctx</emphasis>, size_t <emphasis role="italic">size</emphasis>, const char *<emphasis role="italic">name</emphasis>);</title>

+talloc_set_name_const(ptr, name);</programlisting>
+ </refsect2>
+ <refsect2><title>const char *talloc_get_name(const void *<emphasis role="italic">ptr</emphasis>);</title>
+ <para>
+ This returns the current name for the given talloc pointer,
+ <emphasis role="italic">ptr</emphasis>. See <link
+ linkend="talloc_set_name"><quote>talloc_set_name()</quote></link>
+ for details.
+ </para>
+ </refsect2>
+ <refsect2><title>void *talloc_init(const char *<emphasis role="italic">fmt</emphasis>, ...);</title>
+ <para>
+ This function creates a zero length named talloc context as a top
+ level context. It is equivalent to:
+ </para>
+ <programlisting>talloc_named(NULL, 0, fmt, ...);</programlisting>
+ </refsect2>
+ <refsect2><title>void *talloc_new(void *<emphasis role="italic">ctx</emphasis>);</title>
+ <para>
+ 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.
+ </para>
+ </refsect2>
+ <refsect2><title>(<emphasis role="italic">type</emphasis> *)talloc_realloc(const void *<emphasis role="italic">ctx</emphasis>, void *<emphasis role="italic">ptr</emphasis>, <emphasis role="italic">type</emphasis>, <emphasis role="italic">count</emphasis>);</title>
+ <para>
+ The talloc_realloc() macro changes the size of a talloc pointer.
+ It has the following equivalences:
+ </para>
+ <programlisting>talloc_realloc(ctx, NULL, type, 1) ==> talloc(ctx, type);
+talloc_realloc(ctx, ptr, type, 0) ==> talloc_free(ptr);</programlisting>
+ <para>
+ The <emphasis role="italic">ctx</emphasis> argument is only used
+ if <emphasis role="italic">ptr</emphasis> is not NULL, otherwise
+ it is ignored.
+ </para>
+ <para>
+ 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 <link
+ linkend="talloc_reference"><quote>talloc_reference()</quote></link>).
+ </para>
+ </refsect2>
+ <refsect2><title>void *talloc_realloc_size(const void *ctx, void *ptr, size_t size);</title>
+ <para>
+ the talloc_realloc_size() function is useful when the type is not
+ known so the type-safe talloc_realloc() cannot be used.
+ </para>
+ </refsect2>
+ <refsect2><title>TYPE *talloc_steal(const void *<emphasis role="italic">new_ctx</emphasis>, const TYPE *<emphasis role="italic">ptr</emphasis>);</title>
+ <para>
+ 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.
+ </para>
+ <para>
+ The talloc_steal() function returns the pointer that you pass it.
+ It does not have any failure modes.
+ </para>
+ <para>
+ 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.
+ </para>
+ </refsect2>
+ <refsect2><title>TYPE *talloc_move(const void *<emphasis role="italic">new_ctx</emphasis>, TYPE **<emphasis role="italic">ptr</emphasis>);</title>
+ <para>
+ The talloc_move() function is a wrapper around
+ talloc_steal() which zeros the source pointer after the
+ move. This avoids a potential source of bugs where a
+ programmer leaves a pointer in two structures, and uses the
+ pointer from the old structure after it has been moved to a
+ new one.
+ </para>
+ </refsect2>
+ <refsect2><title>size_t talloc_total_size(const void *<emphasis role="italic">ptr</emphasis>);</title>
+ <para>
+ The talloc_total_size() function returns the total size in bytes
+ used by this pointer and all child pointers. Mostly useful for
+ debugging.
+ </para>
+ <para>
+ 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.
+ </para>
+ </refsect2>
+ <refsect2><title>size_t talloc_total_blocks(const void *<emphasis role="italic">ptr</emphasis>);</title>
+ <para>
+ The talloc_total_blocks() function returns the total memory block
+ count used by this pointer and all child pointers. Mostly useful
+ for debugging.
+ </para>
+ <para>
+ Passing NULL is allowed, but it will only give a meaningful
+ result if talloc_enable_leak_report() or

+ </para>
+ </refsect2>
+ <refsect2 id="talloc_report"><title>void talloc_report(const void *ptr, FILE *f);</title>
+ <para>
+ The talloc_report() function prints a summary report of all
+ memory used by <emphasis role="italic">ptr</emphasis>. One line
+ of report is printed for each immediate child of ptr, showing the
+ total memory and number of blocks used by that child.
+ </para>
+ <para>
+ You can pass NULL for the pointer, in which case a report is
+ printed for the top level memory context, but only if

+ </para>
+ </refsect2>
+ <refsect2 id="talloc_report_full"><title>void talloc_report_full(const void *<emphasis role="italic">ptr</emphasis>, FILE *<emphasis role="italic">f</emphasis>);</title>
+ <para>

+ 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 mounthful 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.
+
+
+=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
+(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,
+ void (*callback)(const void *ptr,
+ 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
+will let you specify the depth and max_depth.
+
+
+=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
+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:

+(type *)talloc_array(const void *ctx, type, uint_t count);
+
+The talloc_array() macro is equivalent to:

+
+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/samba4/source/lib/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 anonymous
+svn. To fetch via svn use the following command:
+
+<pre>
+ svn co svn://svnanon.samba.org/samba/branches/SAMBA_4_0/source/lib/talloc talloc
+ svn co svn://svnanon.samba.org/samba/branches/SAMBA_4_0/source/lib/replace libreplace
+</pre>
+
+To fetch via rsync use this command:
+
+<pre>
