Queues a request for execution by the worker thread.

Syntax

void PutThreadMsg(
    UINT uMsg,
    DWORD dwMsgFlags,
    LPVOID lpMsgParam,
    CAMEvent *pEvent = NULL
);

Parameters

uMsg

Request code.

dwMsgFlags

Optional flags parameter.

lpMsgParam

Optional pointer to a data block containing additional parameters or return values. Must be statically or heap-allocated and not automatic.

Remarks

This member function queues a request for execution by the worker thread. The parameters of this member function will be 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.
