       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 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 support for them.
