The lockf system call is implemented on the Sperry 5000/40, but the unistd.h include file is missing. Owners of the Sperry 5000/40 should create this include file in /usr/include. A sample include file follows. /* @(#)unistd.h 1.0 11/21/86 */ /* added by Stan Barber */ #define F_ULOCK 0 /* unlock */ #define F_LOCK 1 /* lock or sleep */ #define F_TLOCK 2 /* lock or return status */ /* not documented on Sperry */ /* #define F_TEST 3 /* test and return status */
