UNIMPLEMENTED(2)    Linux Programmer's Manual    UNIMPLEMENTED(2)

NAME
       afs_syscall,  break,  ftime,  gtty, lock, mpx, phys, prof,
       profil, stty, ulimit - unimplemented system calls

SYNOPSIS
       Unimplemented system calls.

DESCRIPTION
       These system calls are not implemented in  the  Linux  2.0
       kernel.

RETURN VALUE
       These  system  calls  always  return  -1  and set errno to
       ENOSYS.

NOTES
       Note that ftime(3), profil(3)  and  ulimit(3)  are  imple-
       mented as library functions.

       Some  system calls, like ioperm(2), iopl(2), ptrace(2) and
       vm86(2) only exist on certain architectures.

       Some    system    calls,    like    ipc(2)    and    {cre-
       ate,init,delete}_module(2)  only exist when the Linux ker-
       nel was built with support for them.
