## Constructor & Destructor Documentation

CPLWorkerThreadPool::CPLWorkerThreadPool | ( |  | ) |

Instantiate a new pool of worker threads.

The pool is in an uninitialized state after this call. The Setup() method must be called.

CPLWorkerThreadPool::~CPLWorkerThreadPool | ( |  | ) |

Destroys a pool of worker threads.

Any still pending job will be completed before the destructor returns.

## Member Function Documentation

bool CPLWorkerThreadPool::Setup | ( | int | nThreads,
|  | CPLThreadFunc | pfnInitFunc,
|  | void ** | pasInitData
| ) |  |

Setup the pool.

Parameters

  nThreads | Number of threads to launch
  pfnInitFunc | Initialization function to run in each thread. May be NULL
  pasInitData | Array of initialization data. Its length must be nThreads, or it should be NULL.

Returns
  true if initialization was successful.

bool CPLWorkerThreadPool::SubmitJob | ( | CPLThreadFunc | pfnFunc,
|  | void * | pData
| ) |  |

Queue a new job.

Parameters

  pfnFunc | Function to run for the job.
  pData | User data to pass to the job function.

Returns
  true in case of success.

bool CPLWorkerThreadPool::SubmitJobs | ( | CPLThreadFunc | pfnFunc,
|  | const std::vector< void * > & | apData
| ) |  |

Queue several jobs.

Parameters

  pfnFunc | Function to run for the job.
  apData | User data instances to pass to the job function.

Returns
  true in case of success.

void CPLWorkerThreadPool::WaitCompletion | ( | int | nMaxRemainingJobs = `0` | ) |

Wait for completion of part or whole jobs.

Parameters

  nMaxRemainingJobs | Maximum number of pendings jobs that are allowed in the queue after this method has completed. Might be 0 to wait for all jobs.
