Hi guys,
I have checked the threads and the last one dated in 2003 and hence rather
outdated. I have a telnet server which accepts connection(in an infinite loop)
and
in case the connection is accepted, it process the I/O using the socket in a
nested loop.
while(1){
int s = accept(); //blocks untill the connection is accepted
for(;;){
//runs IO
}
}
I have a slight problem when the remote host closes the connection. I would
want to include a connection status check and jump back
to accept() if the connection is closed from the remote host. Is there anyway
to do this ? It also has to be non-blocking and can be lwip specific.
So far I have heard few suggestions from the old thread :
1. read/write 0 bytes. //blocks ?
2. Use of MSG_PEEK read (in 2003 was not yet implemented ).
I hope to hear your suggestions on the matter and thanks a lot in advance.
