In the linux kernel source tree, look in arch/i386/kernel/entry.S. There you'll find all the syscall entry points. Currently they go all the way to 271. Also look at arch/alpha/kernel/entry.S... Then, in /sys/i386/linux look in syscalls.master. There you'll see we only have syscalls up to 221. See also /sys/alpha/linux... One could: o Add proper prototypes to syscalls.master of the 50 new syscalls we don't know about, o Declare all these syscalls as dummies (see linux_dummy.c) to begin with, o Really implement those syscalls that are used in practice. Syscall 252 is exit_group(2). FYI, -- Marcel Moolenaar USPA: A-39004 marcel@xcllnt.net
