MCIWNDM_GETERROR  C7BANF 

The MCIWNDM_GETERROR message retrieves the last MCI error encountered. You can send this message explicitly or by using the MCIWndGetErrorE7WXAQ macro.

MCIWNDM_GETERROR

wParam = (WPARAM) (UINT) len;

lParam = (LPARAM) (LPVOID) lp;

Parameters

len

Size, in bytes, of the error buffer.

lp

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

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.
