Under linux every things is int 0x80. You put the call number in eax.
My project at http://sourceforge.net/projects/pattod/ had all the linux codes ,but it looks like half the project never made it to cvs. Well that sucks. All the eax values can be found in the assembly file in the kernel. _________________ jInuQ "Perfection is achieved, not when there is nothing more to add, but when there is nothing left to take away." - Antoine de Saint Exupery |

Not so dumb a question. All gas assembly files are .S. I found some sys_call related information that might help. http://www.linuxassembly.org/syscall.html is a link that has the sys_calls. The file you want that has all the sys_calls in it is arch/i386/kernel.entry.S .
The attached file in this topic http://board.flatassembler.net/topic.php?t=55&highlight= has the syscall macros I had been working on. It is not complete ,but give you a stating point. _________________ jInuQ "Perfection is achieved, not when there is nothing more to add, but when there is nothing left to take away." - Antoine de Saint Exupery |

probably a tiny bit late to reply, but just wanted to point out that all the interupt calls to the linux kernel are stored in /usr/include/asm/unistd.h (or similar, depending on where you installed the includes).. in that file, there is a list of lines like such:
#define __NR_open 5 and that shows you what number to put into eax when calling int 0x80 to be able to do different things (eg: that line above is for opening a file, for more info on each, do a man 2 commandname, such as: man 2 open (2 so that it shows you the programmers reference, in case you have a program with the same name as the command)) |
