NAME
WINPROC_SetProc - WINPROC_SetProc
SYNOPSIS
BOOL32 WINPROC_SetProc
(
HWINDOWPROC *pFirst,
WNDPROC16 func,
WINDOWPROCTYPE type,
WINDOWPROCUSER user
);
DESCRIPTION
Set the window procedure for a window or class. There are three tree classes of winproc callbacks:
1) Class -> wp - not subclassed class -> wp -> wp -> wp -> wp - SetClassLong() / /
2) Window -' / - not subclassed window -> wp -> wp ' - SetWindowLong()
3) Timer -> wp - SetTimer()
Initially, winproc of the window points to the current winproc thunk of its class. Subclassing prepends a new thunk to the window winproc chain at the head of the list. Thus, window thunk list includes class thunks and the latter are preserved when the window is destroyed.
