; The below only apply to Linux on IA32.

; General way to do syscalls:

mov eax, <syscall number as below>
mov ebx, arg
mov ecx, arg
mov edx, arg
mov esx, arg
mov edi, arg
int 0x80

; man 2 <syscall name> will tell you arguments and extra information of
; the syscalls

; syscall name                syscall number
