NAME

     afs_syscall, break, ftime, gtty, lock, mpx, phys, prof, pro-
     fil, stty, ulimit - unimplemented system calls


SYNOPSIS

     Unimplemented system calls.


DESCRIPTION

     These system calls are not implemented in the Linux 2.0 ker-
     nel.


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 ioperm(2),  iopl(2),  ptrace(2)  and
     vm86(2) only exist on certain architectures.

     Some      system      calls,      like      ipc(2)       and
     {create,init,delete}_module(2)  only  exist  when  the Linux
     kernel was built with support for them.
