NOT IMPLEMENTED in kernel (always return -ENOSYS)
NAME
afs_syscall, break, ftime, getpmsg, gtty, lock, madvise1, mpx, prof,
profil, putpmsg, security, stty, tuxcall, ulimit, vserver -
unimplemented system calls
SYNOPSIS
Unimplemented system calls.
DESCRIPTION
These system calls are not implemented in the Linux 2.6.22 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) only exist on certain architectures.
Some system calls, like ipc(2), create_module(2), init_module(2), and
delete_module(2) only exist when the Linux kernel was built with support
for them.
SEE ALSO
syscalls(2)
COLOPHON
This page is part of release 3.24 of the Linux man-pages project. A
description of the project, and information about reporting bugs, can
be found at http://www.kernel.org/doc/man-pages/.
Linux 2007-07-05 UNIMPLEMENTED(2)
Also missing from shim:
* epoll_ctl_old
* epoll_wait_old
According to kernel man pages, glibc does not provide wrappers for
every system call (append to this list as you come accross more):
* io_setup
* ioprio_get
* ioprio_set
* sysctl
* getdents
* tkill
* tgkill
Also not in libc (append to this list as you come accross more):
* add_key: (removed in Changelog.17)
* request_key: (removed in Changelog.17)
* keyctl: (removed in Changelog.17)
Although these are Linux system calls, they are not present in
libc but can be found rather in libkeyutils. When linking,
-lkeyutils should be specified to the linker.x
There are probably other things of note, so put them here as you
come across them.
