BloombergLP::bdlmt::MultiQueueThreadPool::drainQueue

Declared in <bdlmt_multiqueuethreadpool.h>

Wait until all jobs in the queue indicated by the specified id are finished. This method simply waits until that queue is empty, without disabling the queue; it may thus wait indefinitely if more jobs are being added. The queue may be enabled or disabled when this method is called. Return 0 on success, and a non‐zero value if the specified queue does not exist or is deleted while this method is waiting. Note that this method waits by repeatedly yielding.

0 on success, and a non‐zero value if the queue does not exist or is deleted while waiting
