◆ try_lock()

int try_lock ( unsigned long timeout )

Try to set a lockfile, blocking or non-blocking. Checks if the lockfile exists and is active.

requires: atomic link(2) syscall.

features:

NFS safe (but leafnode does not work distributed)
stale detection by PID in lock file (may be fooled)

Bug:: Cannot remove stale lock on other machine.

Bug:: Stale detection may be fooled if another process has been assigned the PID that the last caller had.

Returns

0: if locking succeeded
1: if locking failed because the lock is held by someone else and isn't stale
-1: for other errors

Parameters

timeout Timeout, if nonzero, wait at most this many seconds.
