I've noticed, that the preferred syscall method
_syscall:
int 0x80
ret
somewhereinyourcode:
push dword 0 ;exit code 0
mov eax,1 ;SYS_exit
call _syscall
doesn't work, beacuse Leopard uses 64 offsets, so an extra dword will be placed on top of the stack, therefore you'll get "Bad system call" error. The correct way:
push dword 0 ; exit code 0
mov eax,1 ;SYS_exit
push dword 0 ; push 32 bit into the stack, not 64 as a call do
int 0x80
You may use a macro instead of a call to be portable.
