libresolv(4) Kernel Interfaces Manual libresolv(4) NAME libresolv - resolver library SYNOPSIS cc [ flag... ] file... -lresolv -lsocket-lnsl [ library... ] #include <sys/types.h> #include <netinet/in.h> #include <arpa/nameser.h> #include <resolv.h> DESCRIPTION Functions in this library provide for creating, sending, and interpreting packets to the Internet domain name servers. By convention, libresolv.so is a link to one of the shared object files for the resolver, typically the most recent one. For additional information on shared object interfaces, see intro(4). Interfaces The resolver(3N) manual page, and the system include files, describe the behavior of the functions in libresolv.so.2. The shared object libresolv.so.2 provides the public interfaces defined be- low. SUNW_2.1 (generic): _getlong _getshort _res __dn_skipname __fp_query __hostalias __p_cdname __p_class __p_query __p_rr __p_time __p_type __putlong dn_comp dn_expand h_errno res_init res_mkquery res_send res_search res_query res_querydomain 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.

This file is provided for the purpose of back- wards compatibility. There is no plan to fix any of its defects. The original and complete reference documentation for these routines can only be found in earlier releases.
