BloombergLP::bdlmt::MultiQueueThreadPool::MultiQueueThreadPool

Create a multi‐queue thread pool with the given limits.

Synopsis

Declared in <bdlmt_multiqueuethreadpool.h>

MultiQueueThreadPool(
    bslmt::ThreadAttributes const& threadAttributes,
    int minThreads,
    int maxThreads,
    int maxIdleTime,
    bslma::Allocator* basicAllocator = 0);

Description

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.

Parameters

minThreads
