The CMsgThread class provides support for a worker thread to which requests can be posted asynchronously instead of sent directly. The CAMThread class provides a worker thread to which single requests can be sent. Only one client can make a request at a time, and the client blocks until the worker thread has completed the request. By contrast, the CMsgThread class provides a worker thread to which any number of requests can be posted. The requests (in the form of a CMsg object) are queued and executed in order, asynchronously. No reply or return value is received.
|dwFlags||Flag parameter to the request code.|
|lpParam||Data required by the worker thread as parameter or return values. This data should not be stack-based, as it will be referenced some time after completing the queuing operation.|
|pEvent||Event object that a worker thread can signal to indicate the completion of the operation.|
|uMsg||Request code that is defined by the client of the thread class and understood by the overridden worker thread function.|
|CMsg||Constructs a CMsg object.|
