NAME
       afs_syscall,  break,  fattach,  fdetach,  ftime, getmsg, getpmsg, gtty,
       isastream, lock, madvise1, mpx, prof, profil,  putmsg,  putpmsg,  secu-
       rity, stty, tuxcall, ulimit, vserver - unimplemented system calls
SYNOPSIS
       Unimplemented system calls.
DESCRIPTION
       These system calls are not implemented in the Linux 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 implemented as library
       functions.
       Some system calls,  like  alloc_hugepages(2),  free_hugepages(2),  iop-
       erm(2), iopl(2), and vm86(2) exist only on certain architectures.
       Some  system  calls, like ipc(2), create_module(2), init_module(2), and
       delete_module(2) exist only when the Linux kernel was built  with  sup-
       port for them.
