afs_syscall, break, fattach, fdetach, ftime, getmsg, getpmsg, gtty, isastream, lock, madvise1, mpx, prof, profil, putmsg, putpmsg, security, stty, tuxcall, ulimit, vserver - unimplemented system calls  

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.
