isastream, lock, madvise1, mpx, prof, profil, putmsg, putpmsg, secu-
rity, 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), iop-
erm(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 sup-
port for them.
