Contains the following improvements: * proper layering (finally!) for the registry library. Distinction is now made between 'real' backends (local, remote, wine, etc) and the low-level hive backends (regf, creg, ldb, ...) that are only used by the local registry backend * tests for all important hive and registry operations * re-enable RPC-WINREG tests (still needs more work though, as some return values aren't checked yet) * write support for REGF files * dir backend now supports setting/reading values, creating keys * support for storing security descriptors * remove CREG backend as it was incomplete, didn't match the data model and wasn't used at all anyway * support for parsing ADM files as used by the policy editor (see lib/policy) * support for parsing PREG files (format used by .POL files) * new streaming interface for registry diffs (improves speed and memory usage for regdiff/regpatch significantly) ... and fixes a large number of bugs in the registry code (This used to be commit 7a1eec6358bc863dfc671c542b7185d3e39d7b5a) --- source4/lib/util/become_daemon.c | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) (limited to 'source4/lib/util/become_daemon.c') diff --git a/source4/lib/util/become_daemon.c b/source4/lib/util/become_daemon.c index 2a01cea286..034114eade 100644 --- a/source4/lib/util/become_daemon.c +++ b/source4/lib/util/become_daemon.c @@ -28,7 +28,7 @@ /******************************************************************* Close the low 3 fd's and open dev/null in their place. ********************************************************************/ -static void close_low_fds(BOOL stderr_too) +static void close_low_fds(bool stderr_too) { #ifndef VALGRIND int fd; @@ -65,7 +65,7 @@ static void close_low_fds(BOOL stderr_too) Become a daemon, discarding the controlling terminal. **/ -_PUBLIC_ void become_daemon(BOOL Fork) +_PUBLIC_ void become_daemon(bool Fork) { if (Fork) { if (fork()) { @@ -87,7 +87,7 @@ _PUBLIC_ void become_daemon(BOOL Fork) #endif /* HAVE_SETSID */ /* Close fd's 0,1,2.
