Module Name:
|
|
|
|
IgnoreMCIStop.cpp
|
|
|
|
Abstract:
|
|
|
|
The shim hooks mciSendCommand and ignores MCI_STOP which takes 2-3 seconds
|
|
on my P2-400.
|
|
|
|
Sent to the audio team for fixing, but I'm not optimistic - bug number
|
|
246407.
|
|
|
|
Notes:
|
|
|
|
This cannot be put in the layer, but can apply to more than one app.
