Opening a Compound Device by Using the Filename

The following example opens the waveform-audio device by specifying a waveform-audio file named "TIMPANI.WAV".

UINT wDeviceID;

DWORD dwReturn;

MCI_OPEN_PARMS mciOpenParms;

// Opens a waveform-audio device by specifying the device and filename.

mciOpenParms.lpstrDeviceType = "waveaudio";

mciOpenParms.lpstrElementName = "timpani.wav";

if (dwReturn = mciSendCommand(NULL, MCI_OPEN,


// Error, unable to open device.

// The device opened successfully; get the device ID.

wDeviceID = mciOpenParms.wDeviceID;
