Hi:
I ran into another problem. I try to re-send a packet if I don't
receive ACK from the receiver, so I use a timer with "select".
Assuming my receiver is down (ie I turn it off), so the first timer go
off, no response. When I try to block it again with "select",
"select" return right away, saying that packet (ACK) arrives, I then
try to read from that port with "recvfrom" then I get a "connection
refused" error. Shouldn't "select" return at the second block?
Thanks,
MINH
