Assembly program without syscall for Linux

[Jokovich]

Hello everyone, this is my first post here.                                                                                                                            192.168.1.1         
Is it possible to write a simple assembly program that does nothing and exits immediately, without calling syscalls in Linux?
Thank.

hello sir Jokovich;
By syscall I'm suppose that you are on linux x86-64.
You can call exit function from C library, but, I suppose that internally that do a syscall to exit.
If you're assembling (main) and linking using C library you can do a simple program that have only "ret" instruction that will work, but again, I suppose that internally a syscall to exit is done.
I was thinking in kill signal, terminate process, and other things that I need learn, but, others members are better than me on linux, wait for other answers.

Perhaps it's not the best forum to get an answer on linux ?.

Yes, it's possible, but, unless you're using masm on Linux (which it's not possible at all) or maybe Uasm? you should tell us, which kind of assembler are you using?

masm != nasm != gasm != whatever assembler tool :D

Thank.

I'll bet that you would have more luck with this on a LINUX forum somewhere else.
