DSEnumCallback is an application-defined callback function that enumerates the DirectSound drivers. The system calls this function in response to the application's previous call to the DirectSoundEnumerate or DirectSoundCaptureEnumerate function.
BOOL DSEnumCallback(
LPGUID lpGuid,
LPCSTR lpstrDescription,
LPCSTR lpstrModule,
LPVOID lpContext
);
Returns TRUE to continue enumerating drivers, or FALSE to stop.
The application can save the strings passed in the lpstrDescription and lpstrModule parameters by copying them to memory allocated from the heap. The memory used to pass the strings to this callback function is valid only while this callback function is running.
