Locks, unlocks, and tests for locks on a Unix file. Calling syntax is
'lockf(fd,cmd,size)', where fd and cmd are ints, and size is a long.

Command tokens are:

   F_ULOCK 0 /* unlock a previously locked section */
   F_LOCK  1 /* lock a section for exclusive use */
   F_TLOCK 2 /* test and lock a sexction (non-blockking) */
   F_TEST  3 /* test section for other processes' locks */

I'm sure you could implement this with SS_LOCK etc on an RBF device.
