Remarks

This member function queues a request for execution by the worker thread. The parameters of this member function are queued (in a CMsg object) and passed to the CMsgThread::ThreadMessageProc member function of the worker thread.

This member function returns immediately after queuing the request and does not wait for the thread to fulfill the request. The CMsgThread::ThreadMessageProc member function of the derived class defines the four parameters.

This member function uses a multithread safe list, so multiple calls to this member function from different threads can be made safely.

Requirements

Windows Embedded CE Windows CE 2.12 and later
Note Microsoft DirectShow applications and DirectShow filters have different include file and Library requirements
