DESCRIPTION
       The routines described in this manual page are part of the InterNetNews
       library, libinn(3).  They are replacements for the ``clientlib'' part
       of the NNTP distribution, and are intended to be used in building
       programs like rrn.

       Getserverbyfile calls GetConfigValue to get the name of the local NNTP
       server.  It returns a pointer to static space.  The file parameter is
       ignored.

       Server_init opens a connect to the NNTP server at the specified host.
       It returns the server's response code or -1 on error.  If a connection
       was made, then ser_rd_fp and ser_wr_fp can be used to read from and
       write to the server, respectively, and ser_line will contain the
       server's response.  Ser_line can also be used in other routines.

       Handle_server_response decodes the response, which comes from the
       server on host.  If the client is authorized, it returns 0.  A client
       that is only allowed to read is authorized, but handle_server_response
       will print a message on the standard output.  If the client is not
       authorized to talk to the server, then a message is printed and the
       routine returns -1.

       Put_server sends the text in buff to the server, adding the necessary
       NNTP line terminators, and flushing the I/O buffer.

       Get_server reads a line of text from the server into buff, reading at
       most buffsize characters.  Any trailing \r\n terminators are stripped
       off.  Get_server returns -1 on error.

       Close_server sends a ``quit'' command to the server and closes the
       connection.
