[asio-users] R: Use of UDP socket

[Gatti G. <Gia...@fi...>]

I found the solution for the first question: just to call explicitly desctructors and constructors of endpoint and socket, like for the pointers. Probably this "special" methods do something more than calling individually the various methods.

Oggetto: Use of UDP socket

Hello,

I have two questions on the use of the UDP socket.

The first one: how can I close and restart a connection on a different port?
I tried to call the cancel, close and shutdown methods and then call the connect method, but on this method an exception is thrown.
A solution I found is to use the socket as a pointer and, consequently, delete it when I want to close the connection and call the constructor with the new parameters. I think that this is a workaround, but it should be possible to do it without the use of a pointer.

The second one: the socket constructor and the asynch_receive_from method need an endpoint as a parameter. Why? I think it is redundant, only on the socket constructor is needed.

Thank you so much in advance for the suggestions,
Gianluca
