INTERFACES

The shared object libresolv.so.2 provides the public interfaces defined below. See Intro(3) for additional information on shared object interfaces.

__dn_skipname	__fp_query
__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

Programs are expected to use the aliases defined in <resolv.h> rather than calling the "__" prefixed procedures, as indicated in the following table. Use of the routines in the first column is discouraged.

FUNCTION REFERENCED	ALIAS TO USE
__dn_skipname	dn_skipname
__fp_query	fp_query
__putlong	putlong
__p_cdname	p_cdname
__p_class	p_class
__p_time	p_time
