WinDefAVioWindowProc

This call invokes the default AVIO window procedure.

Syntax

WinDefAVioWindowProc (hwnd, msg, mp1, mp2)

Parameters

hwnd (HWND) - input

Window handle

msg (USHORT) - input

Message identity

mp1 (MPARAM) - input

Parameter 1

mp2 (MPARAM) - input

Parameter 2

Return

mresreply (MRESULT) - return

Remarks

Applications using AVIO must pass all WM_SIZE messages for the window with which the AVIO presentation space is associated to this routine, using the same parameters as are received in the WM_SIZE message. This routine maintains the window size data in the presentation space, and must be called before the application accesses the window.

This call is not a replacement for WinDefWindowProc, which must also be called as usual, to process any messages that have not been handled by the application's window procedure.
