* Name: timer_delete
|
|
*
|
|
* Description:
|
|
* The timer_delete() function deletes the specified timer, timerid, previously
|
|
* created by the timer_create() function. If the timer is armed when
|
|
* timer_delete() is called, the timer will be automatically disarmed before
|
|
* removal. The disposition of pending signals for the deleted timer is
|
|
* unspecified.
|
|
*
|
|
* Parameters:
|
|
* timerid - The per-thread timer, previously created by the call to
|
|
* timer_create(), to be deleted.
|
|
*
|
|
* Return Value:
|
|
* If the call succeeds, timer_create() will return 0 (OK). Otherwise, the
|
|
* function will return a value of -1 (ERROR) and set errno to indicate the
|
|
* error.
|
|
*
|
|
* EINVAL - The timer specified timerid is not valid.
|
|
*
|
|
* Assumptions:
|
|
*
