CMsg

CMsg class

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.

Data MembersDescription
dwFlagsFlag parameter to the request code.
lpParamData 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.
pEventEvent object that a worker thread can signal to indicate the completion of the operation.
uMsgRequest code that is defined by the client of the thread class and understood by the overridden worker thread function.
Member FunctionsDescription
CMsg Constructs a CMsg object.
