The caller should specify a size that is greater than or equal to the buffer size retrieved by the DRV_QUERYDEVICEINTERFACESIZE message. This is an input parameter to the function. If the device has no device interface, the string length is zero.įor DRV_QUERYDEVICEINTERFACE, dwParam2 specifies the buffer size in bytes. The DRV_QUERYDEVICEINTERFACE message queries for the device-interface name of a waveIn, waveOut, midiIn, midiOut, or mixer device.įor DRV_QUERYDEVICEINTERFACE, dwParam1 is a pointer to a caller-allocated buffer into which the function writes a null-terminated Unicode string containing the device-interface name.
