EmulatePlaySound.cpp
|
|
|
|
Abstract:
|
|
|
|
If an app calls PlaySound with a SND_LOOP flag, the sould plays
|
|
continuously until PlaySound is called with a NULL sound name. Win9x will
|
|
automatically stop the sound if a different sound is played. This shim
|
|
will catch all PlaySound calls, remember the current sound and
|
|
automatically stop it if a different sound is to be played.
