* 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: |
|
* |
|
