#include <time.h> int timer_delete(timer_t timerid);
The timer_delete() function deletes the specified timer, timerid, previously created by the timer_create(3C) function. If the timer is armed when timer_delete() is called, the behavior will be as if the timer is automatically disarmed before removal. The disposition of pending signals for the deleted timer is unspecified.
If successful, the function returns 0. Otherwise, the function returns −1 and sets errno to indicate the error.
The timer_delete() function will fail if:
The timer ID specified by timerid is not a valid timer ID.
The timer_delete() function is not supported by the system.
