Re: [Pixil-devel] ask for help

:     i guest the side effect of   wirte(sock, 0, 0)  is to make this sock 
: readable, so than when some packet queued, it make the 
: sock readable, so when client use select(...) call, it will return 
: immedialely, not blocked forever if no new packet in, and 
: have chance to get packet queued, if it right? 

I believe that the write is to trigger any pending selects
to unblock their threads/processes.
