Synopsis

Unimplemented system calls.

Description

These system calls are not implemented in the Linux 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) 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.
