	Quick Info

The MCIWndGetError macro retrieves the last MCI error encountered. You can use this macro or explicitly send the MCIWNDM_GETERROR message.

LONG MCIWndGetError(

hwnd,
lp,
len
);

Parameters
hwnd

Handle of the MCIWnd window.

Address of an application-defined buffer used to return the error string.

len

Size, in bytes, of the error buffer.

Return Values

Remarks
If lp is a valid pointer, a null-terminated string corresponding to the error is returned in its buffer. If the error string is longer than the buffer, MCIWnd truncates it.
