Update.
1999-07-26 Ulrich Drepper <drepper@cygnus.com> * sysdeps/generic/clock_getres.c: New file. * sysdeps/generic/clock_gettime.c: New file. * sysdeps/generic/clock_settime.c: New file. * sysdeps/generic/timer_create.c: New file. * sysdeps/generic/timer_delete.c: New file. * sysdeps/generic/timer_getoverr.c: New file. * sysdeps/generic/timer_gettime.c: New file. * sysdeps/generic/timer_settime.c: New file. * sysdeps/generic/bits/time.h: Define __clockid_t, __timer_t, CLOCK_REALTIME, and TIMER_ABSTIME. * sysdeps/mach/hurd/bits/time.h: Likewise. * sysdeps/unix/sysv/linux/alpha/bits/time.h: Likewise. * sysdeps/unix/sysv/linux/bits/time.h: Likewise. * sysdeps/unix/sysv/linux/bits/posix_opt.h: Define _POSIX_TIMERS. * sysdeps/unix/sysv/linux/bits/siginfo.h: Define si_timer1 and si_timer2. * sysdeps/unix/sysv/linux/syscalls.list: Add clock and timer syscalls. * time/Makefile (routines): Add clock_getres, clock_gettime, clock_setres, timer_create, timer_delete, timer_getoverr, timer_gettime, and timer_settime. * time/time.h: Define clockid_t, timer_t, and struct itimerspec for POSIX.1b. Add prototypes for clock and timer functions.
