+.P
+void endnetent(void);
+struct netent *getnetbyaddr(uint32_t \fInet\fP, int \fItype\fP);

+.SH DESCRIPTION
+These functions shall retrieve information about networks. This
+information is considered to be stored in a database that can be
+accessed sequentially or randomly. The implementation of this database
+is unspecified.
+.P
+The
+\fIsetnetent\fR()
+function shall open and rewind the database. If the
+.IR stayopen
+argument is non-zero, the connection to the
+.IR net
+database shall not be closed after each call to
+\fIgetnetent\fR()
+(either directly, or indirectly through one of the other
+.IR getnet* (\|)
+functions), and the implementation may maintain an open file descriptor
+to the database.
+.P
+The
+\fIgetnetent\fR()
+function shall read the next entry of the database, opening and
+closing a connection to the database as necessary.
+.P
+The
+\fIgetnetbyaddr\fR()
+function shall search the database from the beginning, and find the
+first entry for which the address family specified by
+.IR type
+matches the
+.IR n_addrtype
+member and the network number
+.IR net
+matches the
+.IR n_net
+member, opening and closing a connection to the database as necessary.
+The
+.IR net
+argument shall be the network number in host byte order.
+.P
+The
+\fIgetnetbyname\fR()
+function shall search the database from the beginning and find the
+first entry for which the network name specified by
+.IR name
+matches the
+.IR n_name
+member, opening and closing a connection to the database as necessary.
+.P
+The
+\fIgetnetbyaddr\fR(),
+\fIgetnetbyname\fR(),
+and
+\fIgetnetent\fR()
+functions shall each return a pointer to a
+.BR netent
+structure, the members of which shall contain the fields of an entry in
+the network database.
+.P
+The
+\fIendnetent\fR()
+function shall close the database, releasing any open file descriptor.
+.P
+These functions need not be thread-safe.
+.SH "RETURN VALUE"
+Upon successful completion,
+\fIgetnetbyaddr\fR(),
+\fIgetnetbyname\fR(),
+and
+\fIgetnetent\fR()
+shall return a pointer to a
+.BR 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 shall be returned.
+.P
+The application shall not modify the structure to which the return
+value points, nor any storage areas pointed to by pointers within the
+structure. The returned pointer, and pointers within the structure,
+might be invalidated or the structure or the storage areas might be
+overwritten by a subsequent call to
+\fIgetnetbyaddr\fR(),
+\fIgetnetbyname\fR(),
+or
+\fIgetnetent\fR().
+The returned pointer, and pointers within the structure, might also be
+invalidated if the calling thread is terminated.
