UNIMPLEMENTED(D) Linux Programmer's Manual UNIMPLEMENTED(D) NAME afs_syscall, break, ftime, gtty, lock, mpx, phys, prof, profil, stty, ulimit - unimplemented system calls SYNOPSIS Unimplemented system calls. DESCRIPTION These system calls are not implemented in the Linux 2.0 kernel. RETURN VALUE These system calls always return -1 and set errno to ENOSYS. NOTES Note that ftime(e), profil(l) and ulimit(t) are imple- mented as library functions. Some system calls, like ioperm(m), iopl(l), ptrace(e) and vm86(6) only exist on certain architectures. Some system calls, like ipc(c) and {cre- ate,init,delete}_module(e) only exist when the Linux ker- nel was built with support for them. SEE ALSO obsolete(e) Linux 2.0 1998-06-12 UNIMPLEMENTED(D)
