MCIWNDM_GETERROR message
The MCIWNDM_GETERROR message retrieves the last MCI error encountered. You can send this message explicitly or by using the MCIWndGetError macro.
MCIWNDM_GETERROR
wParam = (WPARAM) (UINT) len;
lParam = (LPARAM) (LPVOID) lp;
Parameters
-
len
-
Size, in bytes, of the error buffer.
-
lp
-
Pointer to an application-defined buffer used to return the error string.
Return Value
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.
