When using a window procedure, do I need to clean up the stack or will
windows clean up the stack for me? Do I need the RET 16 or can I just
RET?
For example:
WndProc:
push ebp
mov ebp, esp
cmp [ebp+12], dword WM_CREATE ; window message
jz wm_create
jmp default
wm_create:
jmp default
default:
push dword [ebp+20]
push dword [ebp+16]
push dword [ebp+12]
push dword [ebp+8]
call [DefWindowProcA]
leave
ret 16
I don't know about other assemblers, but in MASM you can use a PROTO
to take care of all this automatically.
