NAME: HAS_MESSAGE_PUMP
SYNOPSIS: Message pump for applications
INTERFACE: RunMessagePump() - runs the pump. Pump runs until either it encounters WM_QUIT, or else the client- supplied Finished predicate returns TRUE.
FilterMessage() - client-installable hook into the pump. IsPumpFinished() - client-definable termination predicate, for loops which do not run to the end of the world.
CAVEATS: Descendants of APPLICATION should not replace IsPumpFinished, since they presumably want to run until WM_QUIT.
HISTORY: beng 07-Oct-1991 Created
**************************************************************************/
DLL_CLASS HAS_MESSAGE_PUMP { protected: WPARAM RunMessagePump();
// Customize pump to client's preference
