i have been trying to understand how the system calls are being made by applications and how the kernel reacts to them...this is what i got into my brain.... when an application makes a system call ( for i386) %eax register is filled with the system call number and some other registers are to be given some appropriate values..for example ..if i amke an exit () system call.. then its system call number "1" is filled in %eax and the status code is filled in %ebx... so i want to know what are the requirements for other systems calls to execute ...what all registers they access..any documentation would be a great help....
