MCIWNDM_GETTIMEFORMAT

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
Address of a buffer to contain the null-terminated string form of the time format.

Return Values

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
Bytes MCI_FORMAT_BYTES
Frames MCI_FORMAT_FRAMES
Hours, minutes, seconds MCI_FORMAT_HMS
Milliseconds MCI_FORMAT_MILLISECONDS
Minutes, seconds, frames MCI_FORMAT_MSF

SMPTE 24 MCI_FORMAT_SMPTE_24
SMPTE 25 MCI_FORMAT_SMPTE_25
