The details of that article are given below hope you can search it on web;-) Name: Kernel Mode Driver Tutorial for MASM32 Programmers - Part 1 - The Basics Abstract Four-F URL:http://www.assembly-journal.com/index.php ali
From: Gary G. Little on 8 Jun 2006 14:07 Cripes, if you want to see assembly used in a driver, simple set "USER_C_FLAGS = -FAcs" in your sources file and then load the resulting .COD file in to your editor du jour. Some variation of -FAcs will give you the assembly language itself if you don't want the pesky C. The question is why do you want to do this? Nearly every reason I have seen for using assembly in the kernel has proven to be falacious and mostly a result of a severe misunderstanding of kernel mode. If the thread Ali references is the one I'm thinking of, it was started by a kinder-gartner who thought assembly was much more elegant than C. Unfortunately, those of us who started when only assembly was available for programming anything, unless you wanted to use COBOL, laughed our asses off. -- The personal opinion of Gary G.

From: Peter on 9 Jun 2006 07:00 Dont worry about useless using of assembler, using of this one *.asm among other 20 *.c is in this case needed. Many times I worked with *.cod files, I only fear that in *.asm source must be used some mysterious MASM directives or other thing, because it is part of driver. Yesterday I created one sample function in *.asm and successfuly linked into driver and it was runnable. Before definition of function I used only: ..386 ..model flat, stdcall ..code .... MyFunction But like I mentioned it seems that all these directives are sufficient, but I am not 100% sure about it, even if this part of code is really functional in result NDIS IM driver. In *.cod file are much more directives, I am not so good in MASM to know what of these I must to use also in *.asm source file. It would be suitable to publish some sample driver with source.asm in it, mainly when inline assembler will not be supported in the future. Thanks ! Peter "Gary G.

P> using of this one *.asm among other 20 *.c is in this case needed. Why? Even though Windows NT isn't in practice a portable operating system any more, it still retains all of the capabilities for being portable across CPU architectures, including the availability of processor-neutral functions, callable from the C and C++ languages, for performing all sorts of low-level things that would on other systems be the purview of assembly language code. <URL:http://perl.plover.com./Questions3.html> It's a fair bet that if you explained the actual problem that you are trying to solve, you'd be pointed in the direction of how to do it without need for any assembly language. Stop asking us about chocolate-covered bananas. |
