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. */ /* Please move implemented system call to sys/
