[ Module development - Socket ]

[comput3rz]

After reading the source code available  in "ngx_mail_auth_http_module.c"

 trying to figure out how to make a "basic TCP connection" to 

a backend server, nothing seems clear. I didn't find any simple pattern 

to read/write on a TCP socket, even if there are simple call like

ngx_event_connect_peer() or ngx_close_connection() for connection phase

 and ngx_send|recv / ngx_unix_send|recv / send|recv for reading and writing
on a socket. 

How can I setup a basic TCP socket into my handler which will connect / send
/ recv and then

close the connection ?
