General Purpose Plugin MASM(asm)

[mre521]

Hey if anyone is wondering how to make a general purpose plugin(gen_whatever.dll) in MASM then here is some code that gives you the bare bones you will need to make one.

code:
.386

.model flat,stdcall

option casemap:none



include windows.inc

include user32.inc

include kernel32.inc

include gdi32.inc



includelib \masm32\lib\user32.lib

includelib \masm32\lib\kernel32.lib

includelib \masm32\lib\gdi32.lib



winampGetGeneralPurposePlugin proto

Init proto

Config proto

Quit proto



GPPHDR_VER equ 10h

GEN_INIT_SUCCESS equ 0

GEN_PLUGIN_UNINSTALL_NOW equ 01h

GEN_PLUGIN_UNINSTALL_REBOOT equ 00h



winampGeneralPurposePlugin struct

	version UINT			?

	description PCHAR  		?

	init PVOID				?

	config PVOID			?

	quit PVOID				?

	hwndParent HWND 		?

	hDllInstance HINSTANCE 	?

winampGeneralPurposePlugin ends



.const

.data

szDesc			db "MASM32 Gen Plugin Test",0

plugin winampGeneralPurposePlugin <GPPHDR_VER,offset szDesc,Init,Config,Quit,0,0>

.data?

.code



DllEntry proc hInst: HINSTANCE, reason: DWORD, reserved1: DWORD



    mov     eax,1

    ret



DllEntry Endp



winampGetGeneralPurposePlugin proc

	

	mov eax,offset plugin

	ret



winampGetGeneralPurposePlugin endp



Init proc

	xor eax,eax

	ret

Init endp



Config proc

	ret

Config endp



Quit proc

	ret

Quit endp





End DllEntry

I always wanted to try something like this.

Hey, thanks, this is cool. By MASM do you mean the Microsoft Macro Assembler, i.e. http://en.wikipedia.org/wiki/MASM ? I don't really know anything about this. How common is it to do Winamp development with MASM? Can you explain why you use it instead of other methods?

This page could make a good tutorial for doing MASM on the Winamp Wiki - http://dev.winamp.com/wiki/ . Would you mind if we started a page for it there?

By MASM do you mean the Microsoft Macro Assembler...

It is assembly language.

MASM is assembly language.

Er, yes. Is it very common to do Winamp development in assembly? What would make someone choose assembly rather than writing C code?

not generally, there are a few but there's more chance of people doing plugins in delphi than in assembler only from my experience.

From my sources here; it deals with computer hardware in a very intimate way. It can run faster and take up less space in memory. I'd say for Winamp if one is considering controlling external devices which I am very sure there are c/c++ variants out there dependent on 3rd party modules.

I have never gone beyond simple std::in std:ut variants in assembly. I could not find any official support for it, the downloads I found were harmful. I don't know if Microsoft still support it. Just as earlier i tried to assemble the code above I got a fatal A1000: cannot open file : windows.inc which I searched for and nowhere to be found in my library, checked the internet and I was presented with a "slightly modified" one. I'd really appreciate it if I could get links to reliable MASM library.

Have you tried those already? Or is that not what you're looking for?

[griffins_Grader]

as per Microsoft downloads I have the tools already.
