how to define a pointer to an imported function as member of a struct?
for example, can it be invoked like this?
struct funstruct

func1 rd 1
func2 rd 2
ends

mystruct funstruct MessageBox,ExitProcess

invoke [mystruct+funstruct.func1], NULL, "ok", "ok", MB_OK

invoke will already do the memory lookup for you so you can just do this:

Code:

mov eax, [MessageBox]
mov [mystruct.func1],eax
...
invoke mystruct.func1, NULL, "ok", "ok", MB_OK
