MCIWNDM_GETTIMEFORMAT message
The MCIWNDM_GETTIMEFORMAT message retrieves the current time format of an MCI device in two forms: as a numerical value and as a string. You can send this message explicitly or by using the MCIWndGetTimeFormat macro.
MCIWNDM_GETTIMEFORMAT
wParam = (WPARAM) (UINT) len;
lParam = (LPARAM) (LPSTR) lp;
Parameters
-
len
-
Size, in bytes, of the buffer.
-
lp
-
Pointer to a buffer to contain the null-terminated string form of the time format.
Return Value
Returns an integer corresponding to the MCI constant defining the time format.
Remarks
If the time format string is longer than the return buffer, MCIWnd truncates the string.
An MCI device can support one or more of the following time formats.
| Time format | MCI constant |
