Remarks Note that WaitMessage does not return if there is unread input in the message queue after the thread has called a function to check the queue. This is because functions such as PeekMessage , GetMessage , GetQueueStatus , WaitMessage, MsgWaitForMultipleObjects , and MsgWaitForMultipleObjectsEx check the queue and then change the state information for the queue so that the input is no longer considered new. A subsequent call to WaitMessage will not return until new input of the specified type arrives. The existing unread input (received prior to the last time the thread checked the queue) is ignored.

The WaitMessage function suspends the thread and does not return until a new message is placed in the thread's message queue.
