问题 I am using boost::asio to make a synchronous TCP socket connection to a node.js TCP server application that runs on the same computer. I am using Embarcadero RAD studio XE4 on Windows building 64 bit application that uses the Embarcadero integrated boost version 1.50. Things work fine except when the node.js TCP server shuts down. When this occurs my C++ client application does not detect the disconnection when I read from the socket. However, it does detect the disconnection when I write to
