* 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.
|
|
*
|
|
* Input Parameters:
|
|
* timerid - The per-thread timer, previously created by the call to
|
|
* timer_create(), to be deleted.
|
|
*
|
|
* Returned 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:
|
|
