svn commit: r543334 - /apr/apr/branches/1.2.x/locks/win32/proc_mutex.c

[wr...@apache.org]

Author: wrowe
Date: Thu May 31 17:13:57 2007
New Revision: 543334

URL: http://svn.apache.org/viewvc?view=rev&rev=543334
Log:
apr_proc_mutex_child_init calls unimplemented OpenMutexW and will fail to
compile on Windows CE.  The patch implements the expected behavior of
OpenMutexW by calling CreateMutex (which will open an existing mutex or 
create one if it doesn't exist) and close the mutex and return an error 
unless CreateMutex indicated that the mutex already existed.
