Description:
The timer_getexpstatus() function gets the expiry status of
the time with the ID given by timerid.
Note:
- This function is based on a POSIX draft.
If you want your code to be more portable, then instead of calling
timer_getexpstatus(), call
timer_gettime()
and check the amount of time left on the timer.
- In order to get timer information, your process must have the
PROCMGR_AID_TIMER ability enabled.
For more information, see
procmgr_ability().
Returns:
- 0
- The timer has expired.
- -1
- An error occurred
(errno is set).
Errors:
- EINVAL
- The timer specified by timerid doesn't exist.
- EPERM
- The calling process doesn't have the required permission; see
procmgr_ability().
