* lib/libsocket/inet/getservbyname_r.c
*
* getservbyname_r() is defined in this file. It is implemented on top of
* _get_hostserv_inetnetdir_byname() which is also used to implement
* netdir_getbyname() for inet family transports. In turn the common code
* uses the name service switch policy for "hosts" and "services" unless
* the administrator chooses to bypass the name service switch by
* specifying third-party supplied nametoaddr libs for inet transports
* in /etc/netconfig.
*
* getservbyport_r() is similarly related to _get_hostserv_inetnetdir_byaddr()
* and netdir_getbyaddr();
*
* The common code lives in lib/libnsl/nss/netdir_inet.c.
*
* getservent_r(), setservent() and endservent() are *not* implemented on top
* of the common interface; they go straight to the switch and are
* defined in getservent_r.c.
*
* There is absolutely no data sharing, not even the stayopen flag or
* enumeration state, between getservbyYY_r() and getservent_r();
