If this semaphore is initially disabled, or becomes disabled while blocking, return `e_DISABLED` with no effect on the count. Otherwise, block until the count of this semaphore is a positive value or the specified `absTime` timeout expires. If the count of this semaphore is a positive value, return 0 and atomically decrement the count. If the `absTime` timeout expires, return `e_TIMED_OUT` with no effect on the count. Return `e_FAILED` if an error occurs. `absTime` is an _absolute_ time represented as an interval from some epoch, which is determined by the clock indicated at construction (see {Supported Clock‐Types} in the component documentation).
