NAMEtimer_create — create a per-process timer
LIBRARYStandard C Library (libc, -lc)
timer_create(clockid_t clockid, struct sigevent * restrict evp, timer_t * restrict timerid);
DESCRIPTIONThe 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.
RETURN VALUESIf successful, the timer_create() function returns 0, and fills in the timerid argument with the id of the new timer that was created. Otherwise, it returns -1, and sets errno to indicate the error.
ERRORSThe timer_create() function will fail if:
- The system is out of resources to satisfy this request, or the process has created all the timers it is allowed.
- The argument clockid is not a valid clock id.
