	Quick Info

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.

Address of the application-defined buffer used to return the mode.

Return Values
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 ready	MCI_MODE_NOT_READY
open	MCI_MODE_OPEN
paused	MCI_MODE_PAUSE
playing	MCI_MODE_PLAY
recording	MCI_MODE_RECORD
seeking	MCI_MODE_SEEK
stopped	MCI_MODE_STOP
