SYNOPSISUnimplemented system calls.

---

DESCRIPTIONThese system calls are not implemented in the Linux kernel.

---

RETURN VALUEThese system calls always return −1 and set errno to ENOSYS.

---

NOTESNote 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.
