__hostalias __p_cdname
__p_class __p_query
__p_time __p_type
__putlong _getlong
_getshort _res
dn_comp dn_expand
fp_resstat h_errno
herror hstrerror
res_hostalias res_init
res_mkquery res_nclose
res_ninit res_nmkquery
res_nquery res_nquerydomain
res_nsearch res_nsend
res_nsendsigned res_query
res_querydomain res_search
res_send res_update
