Yo can try to read the socket, if it gives a 0 in
bytes received it means the connection is broken. It
says so in the PalmReference.pdf
You can use the netIOFlagPeek flag to read from the
socket but not erase the data from the buffer.
msg = MemPtrNew(len);
size =
NetLibReceive(AppNetRefnum,sock,msg,len,netIOFlagPeek,0,0,0,&errno);
if (size == 0)
{
close_connection();
}
MemPtrFree(msg);
