Description:
Waits for an inter-application message, and gets its content. For sending messages, check SendAPMessage. You can check if there is a message waiting to be read, using PeekAPMessage to avoid a blocking call. Also get_message will intercept application messages, besides remote client messages.
Return value:
Returns the size in bytes of the message. If 0, then an error was encountered.
