getnetent(3N-xs)              (X/OPEN SOCKETS)             getnetent(3N-xs)

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

SYNOPSIS
     cc [flag ...] file ... -lxnet [library ...]

     #include <netdb.h>

     void endnetent(void);

     struct netent *getnetbyaddr(inaddrt 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 naddrtype member and the network number net matches
     the nnet 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 nname member, opening a connection to the database if
     necessary.

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

     The endnetent function closes the database.

RETURN VALUE
     On successful completion, getnetbyaddr, getnetbyname and getnetent
     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.

APPLICATION 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.
