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