src/xpdev filewrap.c 1.46 1.47
Update of /cvsroot/sbbs/src/xpdev
In directory cvs:/home/rswindell/sbbs/src/xpdev

Modified Files:
	filewrap.c 
Log Message:
Use "Open file description locks" when available (i.e. Linux 3.15 and later)
This variation on fcntl() record-locks resolves multiple-thread / forking
issue with region locks. No longer falls back to using flock() (whole-file
locks), when OFD locks are available and used successfully. At the least,
this should provide a performance boost for shared files using region
locks (on Linux). No change for Windows (region locks already worked sanely
among multiple threads) and other *nixes (that use POSIX fcntl() locks
only).
