+.SH DESCRIPTION
+The
+.IR getnetent ,
+.IR getnetbyname ,
+and
+.I getnetbyaddr
+subroutines
+each return a pointer to an object with the
+following structure
+containing the broken-out
+fields of a line in the 
+.I networks 
+database.

+	int	n_addrtype;	/* net number type */

+.PP
+The members of this structure are:
+.TP \w'n_addrtype'u+2n
+n_name
+The official name of the network.
+.TP \w'n_addrtype'u+2n
+n_aliases
+A zero terminated list of alternate names for the network.
+.TP \w'n_addrtype'u+2n
+n_addrtype
+The type of the network number returned: AF_INET.
+.TP \w'n_addrtype'u+2n
+n_net
+The network number.  Network numbers are returned in machine byte
+order.
+.PP
+If the
+.I stayopen
+flag on a 
+.I setnetent
+subroutine is NULL, the
+.I networks
+database is opened.  Otherwise the
+.I setnetent
+has the effect of rewinding the 
+.I networks 
+database.
+The
+.I endnetent
+may be called to
+close the 
+.I networks 
+database when processing is complete.
+.PP
+The
+.I getnetent
+subroutine simply reads the next
+line while
+.I getnetbyname
+and
+.I getnetbyaddr
+search until a matching
+.I name
+or
+.I net
+number is found
+(or until EOF is encountered).  The \fItype\fP must be AF_INET.
+The
+.I getnetent
+subroutine keeps a pointer in the database, allowing
+successive calls to be used 
+to search the entire file.
+.PP
+A call to
+.I setnetent
+must be made before a
+.I while
+loop using
+.I getnetent
+in order to perform initialization and an
+.I endnetent
+must be used after the loop.  Both
+.I getnetbyname
+and
+.I getnetbyaddr
+make calls to
+.I setnetent
+and
+.I endnetent .
+.SH FILES
+.I /etc/networks
+.SH DIAGNOSTICS
+Null pointer (0) returned on EOF or error.

+.SH HISTORY
+The getnetent(), getnetbyaddr(), getnetbyname(), setnetent(), and
+endnetent() functions appeared in 4.2BSD.
+.SH BUGS
+The data space used by these functions is static; if future use requires the
+data, it should be copied before any subsequent calls to these functions
+overwrite it.  Only Internet network numbers are currently understood.
+Expecting network numbers to fit in no more than 32 bits is probably naive.
