Using conn->client->fd

[Eric Cholet <ch...@logilune.com>]

I am writing a chat application. One of it's components waits on data from 
the chat server and sends it to the client (browser). I need to know when 
the client has disconnected. I get the browser's fd from 
r->connection->client->fd, and do a select() waiting for either the browser 
or the chat server to have data available. Even though I'm not reading from 
the browser a hangup will be seen as a zero length packet becoming 
available for reading.

Is it legit to access conn->client->fd ? It seems there ought to be an 
ap_function instead, unless my approach is wrong and there's a better way 
to solve my problem.

Gday,

	Use the conn->client->flags value to determine wether the connection
has cloesd. The flag youre looking for is B_EOF. Anyways, just a quick 

	if ( conn->client->flags & B_EOF ) 

	should yeild the test required. There is a wealth of information
in the flag fields that you can use. A couple of handy ones include 
B_RDERR, B_WRERR, B_OUT ( no further output possible ). Consult buff.h
for details...

Cheers Mik.
