Instead, they should access 71its functions using the architecture-dependent 72library. 73.Sh RETURN VALUES 74See the manual pages for specific architecture-dependent system calls 75for information about their return values. 76.Sh SEE ALSO 77.Xr i386_get_ioperm 2 , 78.Xr i386_get_ldt 2 , 79.Xr i386_vm86 2 80.Sh HISTORY 81This manual page was taken from 82.Nx . 83
