Unimplemented system calls.
These system calls are not implemented in the Linux kernel.
These system calls always return -1 and set errno to ENOSYS.
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.
This page is part of release 4.16 of the Linux man-pages project. A
description of the project, information about reporting bugs, and the latest
version of this page, can be found at https://www.kernel.org/doc/man-pages/.
