    <p>Now I'm writing a proxy server for a specify true server.</p> <p>The architecture of the system can be represent by the graph below:</p> <p>(I actually use multi-threads to handle all clients.)</p> <p><strong>'client A'</strong> ←––––– –––––→ <strong>'proxy server'</strong> ←––––– –––––→ <strong>'true Server'</strong> 　　　 </p> <hr> <p>I use "libev.h" to implement it, so one event need to listen two socket.</p> <p>I find some example like:</p> <pre><code>struct MYIO w { ev_io io; int serverfd; int clientfd; } int main() { ... struct MYIO w; w.clientfd = new_tcp_client ("127.0.0.1", 12346); ev_io_init (&amp;w.io, client2proxy_func, clientfd, EV_READ); ev_io_start (loop, &amp;w_io); ev_timer_init (&amp;timeout_watcher, timer_func, 5, 0.); ev_timer_start (loop, &amp;timeout_watcher); ... } </code></pre> <p>This only for one io event.</p> <p>If I want to wait two io_ev then it didn't work... like this below:</p> <p>(I also try some different way but all failed.)</p> <pre><code>... w.clientfd = new_tcp_client ("127.0.0.1", 12346); w.serverfd = new_tcp_server ("127.0.0.1", 12345); ev_io_init (&amp;w.io, client2proxy_func, clientfd, EV_READ); ev_io_start (loop, &amp;w_io); ev_io_init (&amp;w.io, proxy2server_func, serverfd, EV_READ); ev_io_start (loop, &amp;w_io); ev_timer_init (&amp;timeout_watcher, timer_func, 5, 0.); ev_timer_start (loop, &amp;timeout_watcher); ... </code></pre> <p>How to use libev in multi-task?</p> <p>How to use libev for one event, waiting two sockets by two ev_io and ev_watch?</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
