boost::asio 和 send() 的使用

Question

When using a boost::asio::ip::tcp:socket there are many methods one can use to write/send data. There's also asio::write that takes the socket as a parameter, etc. My question is is there any compatibility issues (gotchas) with the boost asio libraries when using the standard send() function?

Should one categorically never use the standard send() function on a boost::asio::ip::tcp:socket ? Or maybe it works fine, but why use send() when you already have everything you could possibly need in this regard within the boost::asio libraries.

Answer 1

You need to use the boost asio send and send_to function for UDP sockets while the write method is used for synchronous stream write ie used for TCP and cannot be used for UDP as it is "stream write".
