CHANGE HISTORY

First released in Issue 5. Included for alignment with the POSIX Realtime Extension.

Issue 6

The timer_delete() function is marked as part of the Timers option.

The [ENOSYS] error condition has been removed as stubs need not be provided if an implementation does not support the Timers option.

IEEE Std 1003.1-2001/Cor 2-2004, item XSH/TC2/D6/139 is applied, updating the ERRORS section so that the [EINVAL] error becomes optional.
