Keywords: lockf news 2.11 Sperry 5000/40

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 */
