Instead, they should access 66its functions using the architecture-dependent 67library. 68.Sh RETURN VALUES 69See the manual pages for specific architecture-dependent function calls 70for information about their return values. 71.Sh SEE ALSO 72.Xr i386_get_ioperm 2 , 73.Xr i386_get_ldt 2 , 74.Xr i386_vm86 2 75.Sh HISTORY 76This manual page was taken from 77.Nx . 78
