C-Type DLL .INC Builder

[Farabi]

 
ompldr.org/vYmMwaA/fTypeINCBuilderl.zip

You know, sometime some library providing a lib that are not compatible with MASM, even worse, some are not even providing it. So Im making a INC builder, typicaly a cumbersome INC file where I get used to it. I hope its usefull for you. I also included a graphic inside the program, just an eye candy to show off  :green

Enjoy.

;Created Using Onan Farabi Tools. Please, Tell anyone that you builded this using my tools, but it is uneneccesary
;Well, at least if you said that, maybe somebody willing to bought me a new laptop, mine is outdated-lol, and almost near it death.
;Also, I want a Playstation 3 and xBOX360, but I dont have money, I prefer my hobby then looking for job, cant help it.
;Created Using INC Builder Specially designed for beeing used with RadAsm. Building: D:\OGLE\Lib\LIBTGA.dll

Im sorry I put an adv on the file, but Im not forcing you to give me anything, if you just want to use it for free, just use it. I had no time do analyze the argument value need to be passed, it is out of my knowledge, but if I know something someday, I'll tell you.

I think Vortex already wrote on:
http://www.vortex.masmcode.com/files/Dll2inc14.zip

Or maybe it's different?

[Farabi]

Almost alike, the difference is, it doesnot create a def or .inc or being used to create a .lib, but generated a code to call directy the function using GetProcAddress, I gave up using MASM tools to build any .lib.

[Farabi]

I saw the pattern how to check how much argument a function was, but Im still scared to implemented it and shared it with you guys. And also, if the address of a function is always static, I will reduce the include file and get rid the GetProcAddress Thingy so you can just directly call without it, thanks to vortex knowledge.
To check the argument, you need to keep track the EBP/ESP value, which mean you need to decode the code of the function, but Im affraid if I did this I will violate the law of the forum, so I did not done it yet.

What are you doing. Creating a dynamic wrapper for dll that was compiled from an open source MIT licensed targa library?

Compile the C file to lib or obj, convert .h with h2incx and you're good to go. :eek

Im too stupid to use the C compiler, it is too complicated, I think it is easier to get the address directly from GetProcAddress and then add it with the base address and put the result on the .data section, so I dont need to use GetProcAddress again and safe space. There is a lot of free library that are not have a good .lib and creating the inc and the lib could kill me.

Okay, I hope it did not break the rules.

Here is some patern:

Push Ebp
mov ebp,esp ; <<< If you see this one, first arg at +8, 2nd and +12 and so on
sub esp,20 ;  << The local variable is about 20 bytes, or even maybe, the local variable start after 20 bytes, so there only 5 arg for this function

mov eax,[esp+4]
mov edx,[esp+8]
call unk_func
ret
; Obviously, it only had 2 parameter, and it did not auto balancing the stack

mov eax,[esp+4]
mov edx,[esp+8]
call unk_func
retn 0C
; Auto balancing function, it had 3 parameter, but only 2 used
