MCIWNDM_GETMODE message

The MCIWNDM_GETMODE message retrieves the current operating mode of an MCI device. MCI devices have several operating modes, which are designated by constants. You can send this message explicitly or by using the MCIWndGetMode macro.



MCIWNDM_GETMODE 
wParam = (WPARAM) (UINT) len; 
lParam = (LPARAM) (LPSTR) lp; 


Parameters

len

Size, in bytes, of the buffer.

lp

Pointer to the application-defined buffer used to return the mode.

Return Value

Returns an integer corresponding to the MCI constant defining the mode.

Remarks

If the null-terminated string describing the mode is longer than the buffer, it is truncated.

Not all devices can operate in every mode. For example, the MCIAVI device is a playback device; it doesn't support the recording mode. The following modes can be retrieved by using MCIWNDM_GETMODE.

Operating mode MCI constant
not readyMCI_MODE_NOT_READY
openMCI_MODE_OPEN
pausedMCI_MODE_PAUSE
playingMCI_MODE_PLAY
recordingMCI_MODE_RECORD
seekingMCI_MODE_SEEK
