This directory contains three example programs.
---------------------------------------------------------------------------
PROGRAM
lookupdns
FILES
lookupdns.c
res.c
USAGE
lookupdns <hostname1> [<hostname2>] ...
DESCRIPTION
This program performs asynchronous DNS host name resolution and reports
IP address for each <hostname> specified as a command line argument.
One ST thread is created for each host name. All threads do host name
resolution concurrently.
---------------------------------------------------------------------------
PROGRAM
proxy
FILES
proxy.c
USAGE
proxy -l <local_addr> -r <remote_addr> [-p <num_processes>] [-S]
-l <local_addr> bind to local address specified as [<host>]:<port>
-r <remote_addr> connect to remote address specified as <host>:<port>
-p <num_processes> create specified number of processes
-S serialize accept() calls from different processes
on the same listening socket (if needed).
DESCRIPTION
This program acts as a generic gateway. It listens for connections to a
local address. Upon accepting a client connection, it connects to the
specified remote address and then just pumps the data through without any
modification.
---------------------------------------------------------------------------
PROGRAM
server
FILES
server.c
error.c
USAGE
server -l <log_directory> [<options>]
-l <log_directory> open all log files in specified directory.
Possible options:
-b <host>:<port> bind to specified address (multiple addresses
are permitted)
-p <num_processes> create specified number of processes
-t <min_thr>:<max_thr> specify thread limits per listening socket
across all processes
-u <user> change server's user id to specified value
-q <backlog> set max length of pending connections queue
-a enable access logging
-i run in interactive mode (useful for debugging)
-S serialize accept() calls from different processes
on the same listening socket (if needed).
DESCRIPTION
This program is a general server example. It accepts a client connection
and outputs a short HTML page. It can be easily adapted to provide
other services.
