BloombergLP::bslmt::FastPostSemaphoreImpl::timedWait

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).
