That's the point. Don't. Use a select, it has a timeout, and accept only if<br>
select shows activity on the listened to socket.</blockquote></div><br></div><div class="gmail_default" style="font-family:tahoma,sans-serif">Not sure, but i believe i used it in the past and have problems with it, We can leave it to silvio to test it :P</div>

A few facts:</div><div><span class="Apple-tab-span" style="white-space:pre"> </span>- You create a listening socket which you pass as an argument to accept().</div><div><span class="Apple-tab-span" style="white-space:pre"> </span>- A socket is a file descriptor.</div><div><span class="Apple-tab-span" style="white-space:pre"> </span>- Select operates on file descriptors. Read the man page of select [<a href="http://linux.die.net/man/2/select">http://linux.die.net/man/2/select</a>] and you'll see that the exact purpose of select is to query whether or not the next IO operation is going to block.<br></div><div><br></div><div>Now that we have established these two facts, I believe that using select before accept to check whether the latter will block is valid logic, wouldn't you say?</div><div><br></div><div>PS: The exact details of this implementation I do not know, I haven't tested.</div><br><div>
