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.
