This allows you to bind the
voipchat
server to127.0.0.1
or::1
.This change is motivated by the following observations of current
voipchat
:When running
voipchat --server
, it was unclear to what socket the server was bound to.Also, the following combination failed for me:
server command:
./voipchat --server
clients command:
./voipchat localhost
Only after changing the client command to
./voipchat 127.0.0.1
could I get working voip.This pr explicitly selects a binding address for the server, so it will never pass
NULL
toSDLNet_CreateDatagramSocket
when creating a server.Perhaps #85 is related.
