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.
