Member Function Documentation

MStatus MThreadPool::init (  )  [static]

Initialize thread pool creation. No threads are created by this call.

Returns:
Examples:

MStatus MThreadPool::newParallelRegion ( MThreadCallbackFunc  func,
void *  data 
) [static]

Creates a new parallel region. All tasks created by createTask() will be added to this region. init() must be called to create the thread pool before calling this function.

Parameters:
[in] func pointer to function to be executed by threads
[in] data data for function
Returns:
Examples:

MStatus MThreadPool::createTask ( MThreadFunc  func,
void *  data,
MThreadRootTask *  root 
) [static]

Add a single task to the parallel region. The parallel region must already have been created by calling newParallelRegion.

Parameters:
[in] func pointer to function to be executed by threads
[in] data data for function
[in] root root task
Returns:
Examples:

MStatus MThreadPool::executeAndJoin ( MThreadRootTask *  root  )  [static]

Run all tasks in the present parallel region to completion. This function must be called from within a function invoked by the method newParallelRegion.

Parameters:
[in] root task to execute
Returns:
Examples:

void MThreadPool::release (  )  [static]

Release decreases the reference count on the thread pool. When the reference count reaches zero the thread pool is deleted.
