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.
