UDP_Bind and IPaddress

Hello everyone,

actually I am coding an app which uses SDL_net with UDP sockets for network
communication. I am now wondering what UDP-Bind does with the IPaddress
object. When calling bind like this:
// const IPaddress address;
ushort er = SDLNet_UDP_Bind(socket, 0, &address);
gcc tells that it is not allowed to pass the IPaddress as const.
Does UDP_Bind actually changes the IPaddress and if not, why it is not
declared as const?
