Instead, they should access 67its functions using the architecture-dependent 68library. 69.Pp 70.Sh RETURN VALUES 71See the manual pages for specific architecture-dependent function calls 72for information about their return values. 73.Sh SEE ALSO 74.Xr i386_get_ioperm 2 , 75.Xr i386_get_ldt 2 , 76.Xr i386_vm86 2 77.Sh HISTORY 78This manual page was taken from 79.Nx . 80
