Hi,
I am having a problem with getting a handle on the example MSVAD (Simple)
audio driver. It is installed using DevCon and working ok.
Using the example application code from
WinDDK\7600.16385.0\src\general\ioctl\wdm, I have tried the following:
HANDLE hDrv = CreateFile(L"\\\\.\\MSVAD (Simple)",
GENERIC_READ|GENERIC_WRITE,
0,
NULL,
CREATE_ALWAYS,
// Also tried OPEN_EXISTING
FILE_ATTRIBUTE_NORMAL, //
Also tried 0
NULL);
Other paths tried:
L"\\\\.\\*MSVADSimple"
L"\\\\.\\MSVAD_Simple"
What path should I pass to CreateFile()?
Thanks,
Jan
