MCIWNDM_GETMODE  1OITT4_ 

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 MCIWndGetMode10E8IQH macro.

MCIWNDM_GETMODE

wParam = (WPARAM) (UINT) len;

lParam = (LPARAM) (LPSTR) lp;

Parameters

len

Size, in bytes, of the buffer.

lp

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:
