udp::endpoint - port change
Hello all, probably trivial but I am currently stuck with this: I create a UDP endpoint via udp::resolver::query query(udp::v4(),IP,port); destinationEndpoint = new udp::endpoint(*resolver.resolve(query)); but after the creation I want to change the port without deleting and recreating it with different parameters. How can I do this ? Thanks in advance, best Alex

You can change the port of an existing endpoint using the port() member function [1]. Creating the endpoint with new seems a bit overkill though. Unless you have a specific reason I wouldn't allocate them on the heap. [1] http://www.boost.org/doc/libs/1_60_0/doc/html/boost_asio/reference/ip__basic... Regards, Maarten
