typedef NTSTATUS SOUND_QUERY_FORMAT_ROUTINE (PLOCAL_DEVICE_INFO, PPCMWAVEFORMAT);
SOUND_QUERY_FORMAT_ROUTINE is the type definition for a function used to determine if a specified wave format is supported.
Parameters
PLOCAL_DEVICE_INFO
Type for a pointer to a LOCAL_DEVICE_INFO structure.
PPCMWAVEFORMAT
