MCIWndGetError macro (vfw.h)

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

Syntax

void MCIWndGetError(
   hwnd,
   lp,
   len
);

Parameters

hwnd

Handle of the MCIWnd window.

lp

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

len

Size, in bytes, of the error buffer.

Return value

None

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.
