NAME
       afs_syscall,  break,  fattach,  fdetach, ftime, getmsg, getpmsg, gtty, isastream, lock, madvise1, mpx, prof, profil, putmsg,
       putpmsg, security, 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), ioperm(2), iopl(2), and vm86(2) exist only on certain  archi‐
       tectures.

       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 support for them.
