I have an application (EXE file without sources) that listen UDP on
port 1812 and when it receive data, it send an UDP paquet back to
sender with same source 1812 port.
I have to do same application but I get exception "already binded" if
I use MySocket.LocalPort:=1812 to send paquet back, if I use
MySocket.LocalPort:=0 it works but on the other application will
simply ignore the paquet as src is not 1812 (this is the way it works,
I cannot change this).
So question is : how to force UDP port source when sending it whenever
this port is used by a listener socket as the other application do ?
May be thru sockaddr_in structure ?
