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 3.54 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/.
