ENDNETENT(3XNET)					      ENDNETENT(3XNET)

NAME
       endnetent,  getnetbyaddr,  getnetbyname, getnetent, setnetent - network
       database functions

SYNOPSIS
       cc [ flag ... ] file ... -lxnet [ library ... ]
       #include <netdb.h>

       void endnetent(void);struct netent *getnetbyaddr(in_addr_t net, int type);

       struct netent *getnetbyname(const char *name);

       struct netent *getnetent(void)

       void setnetent(int stayopen);

DESCRIPTION
       The getnetbyaddr(),  getnetbyname()  and	 getnetent(),  functions  each
       return  a  pointer  to a netent structure, the members of which contain
       the fields of an entry in the network database.

       The getnetent() function reads the next entry of the database,  opening
       a connection to the database if necessary.

       The  getnetbyaddr()  function searches the database from the beginning,
       and finds the first entry for which the	address	 family	 specified  by
       type  matches  the n_addrtype member and the network number net matches
       the n_net member, opening a connection to the  database	if  necessary.
       The net argument is the network number in host byte order.

       The  getnetbyname()  function  searches the database from the beginning
       and finds the first entry for which the network name specified by  name
       matches the n_name member, opening a connection to the database if nec‐
       essary.

       The setnetent() function opens and rewinds the database.	 If the	 stay‐
       open  argument is non-zero, the connection to the net database will not
       be closed after each call to getnetent()	 (either  directly,  or	 indi‐
       rectly through one of the other getnet*() functions).

       The endnetent() function closes the database.

USAGE
       The  getnetbyaddr(),  getnetbyname()  and  getnetent(),	functions  may
       return pointers to static data, which may be overwritten by  subsequent
       calls to any of these functions.

       These functions are generally used with the Internet address family.

RETURN VALUES
       On  successful  completion,  getnetbyaddr(),  getnetbyname() and getne‐
       tent(), return a pointer to a netent structure if the  requested	 entry
       was found, and a null pointer if the end of the database was reached or
       the requested entry was	not  found.   Otherwise,  a  null  pointer  is
       returned.

ERRORS
       No errors are defined.
