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
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
