SirenJukebox2.cpp
|

|
|
|
||
|
|
Abstract:
|
||
|
|
|
||
|
|
This app has a problem with DirectDraw 7.0 and hence we fail the call to
|
||
|
|
GetProcAddress when it asks for DirectDrawCreateEx.
|
||
|
|
|
||
|
|
Notes:
|
||
|
|
|
||
|
|
This is an app specific shim.

03/13/2001 prashkud Created
|
||
|
|
05/04/2001 prashkud Modified to fix a bug if ordinals are passed
|
||
|
|
instead of string addresses. We now imitate
|
||
|
|
the behaviour of the actual GetProcAddress().
