Instead, they should access 70its functions using the architecture-dependent 71library. 72.Sh RETURN VALUES 73See the manual pages for specific architecture-dependent function calls 74for information about their return values. 75.Sh SEE ALSO 76.Xr i386_get_ioperm 2 , 77.Xr i386_get_ldt 2 , 78.Xr i386_vm86 2 79.Sh HISTORY 80This manual page was taken from 81.Nx . 82
