TIMER_CREATE(2) 					      BSD System Calls Manual						   TIMER_CREATE(2)

NAME
     timer_create -- create a per-process timer

LIBRARY
     Standard C Library (libc, -lc)

SYNOPSIS
     #include <time.h>
     #include <signal.h>

     int
     timer_create(clockid_t clockid, struct sigevent * restrict evp, timer_t * restrict timerid);

DESCRIPTION
     The timer_create() function creates a per-process timer using the clock specified in the clockid argument.  If it succeeds, the
     timer_create() function fills in the timerid argument with an id associated with the timer created that can be used by other timer related
     calls.  The clockid must be a valid clock id as defined in <time.h>.  The timer is created in a disarmed state.

     An optional (non-NULL) struct sigevent argument can be specified by the evp argument.  If the evp argument is NULL, then evp->sigev_notify
     defaults to SIGEV_SIGNAL and evp->sigev_value is set to timerid.  Refer to sigevent(3) for more details.

NOTES
     Timers are not inherited after a fork(2) and are disarmed and deleted by an exec(3).

RETURN VALUES
     If successful, the timer_create() function returns 0, and fills in the timerid argument with the id of the new timer that was created.  Oth-
     erwise, it returns -1, and sets errno to indicate the error.

ERRORS
     The timer_create() function will fail if:

     [EAGAIN]		The system is out of resources to satisfy this request, or the process has created all the timers it is allowed.

     [EINVAL]		The argument clockid is not a valid clock id.
