typedef

[RedGhost]

okay well, i am terrible in masm, only coded for one app and it was a hello world app,
and one dll but it was a pre-done basehook  :U
anyways, i am okay in inline asm for c++, well actually no, i am terrible in that aswell!
my question:
    i dont know how to initialize data in masm very well, how would go about doing ->

Code Select Expand


//c++
typedef void ( APIENTRY* func )( arg1, arg2, etc );
func orig;


in masm!

I may be wrong as I don't read C++ properly but it looks like a function with no return value (VOID) and no arguments.

MASM prototypes are in this form,

FuncName [calling convention] PROTO [arg1:DATASIZE, arg2:DATASIZE etc ...]

Calling convention is either C or STDCALL

DATASZIE is any generic ASM date size.

Yeah ,
And you dont have to declare any thing in convention if it is STDCALL and you have declared STDCALL as the default calling convention by .model flat,stdcall . You dont have a whole sh*tload of datatypes like in C++, you just have a DWORD. In asm everything is a DWORD whether it be HICON, HANDLE, HINSTANCE anything. And you don't have to give a return type. Return a value inside the function if you want by putting the value in eax. See Iczelion's tutorials
http://win32asm.cjb.net/ and AoA Book http://webster.cs.ucr.edu/

That looks to me like redefining the void type (? - to be: APIENTRY* func(...))
Anyway, you don't really need to worry about such things in masm - things are whatever type you want :lol
All functions are defined in the same way and they have no actual return type - it's however you treat it :wink

thanks guys, your help and masm programmers guide

problem resolved :)

You want a pointer to a function right? But a pointer is a dword. So the whole thing is just a dword.

yeah thats what i ended up realizing and doing xD
