Can I share boost::asio::tcp::socket object between 2 threads that perform read and write

Question

I have two threads, one sending and another receiving data via TCP socket. I use boost::asio::read() and boost::asio::write() for reading and writing. My question is do I have to guard the access to socket object during read and write operation?

The other case would be what if I have two threads both writing using the same socket object?

Answer 1

The socket is not thread safe when shared between two or more threads. For more information look at the Boost.Asio documentation.
