Declared in `<bdlmt_multiqueuethreadpool.h>`

Construct a `MultiQueueThreadPool` with the specified `threadPool`. Optionally specify a `basicAllocator` used to supply memory. If `basicAllocator` is 0, the default memory allocator is used. The behavior is undefined if `threadPool` is 0. Note that the `MultiQueueThreadPool` is created without any queues. Although queues may be created, `start` must be called before enqueuing jobs.

Construct a `MultiQueueThreadPool` with the specified `threadAttributes`, the specified `minThreads` minimum number of threads, the specified `maxThreads` maximum number of threads, and the specified `maxIdleTime` idle time (in milliseconds) after which a thread may be considered for destruction. Optionally specify a `basicAllocator` used to supply memory. If `basicAllocator` is 0, the currently installed default allocator is used. The behavior is undefined unless `0 <= minThreads`, `minThreads <= maxThreads`, and `0 <= maxIdleTime`. Note that the `MultiQueueThreadPool` is created without any queues. Although queues may be created, `start` must be called before enqueuing jobs.
