SYNOPSIS         top

       Unimplemented system calls.

DESCRIPTION         top

       These system calls are not implemented in the Linux kernel.

RETURN VALUE         top

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

NOTES         top

       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.
