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.
