MCIWndGetError  1MLV438 

The MCIWndGetError macro retrieves the last MCI error encountered. You can use this macro or explicitly send the MCIWNDM_GETERRORH85A4G message.

LONG MCIWndGetError(

    hwnd,

 

    lp,

 

    len

 

   );

 

 

Parameters

hwnd

Handle of the MCIWnd window.

lp

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

len

Size, in bytes, of the error buffer.

 

Return Values

Returns the integer error value if successful.

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.
