How to Gracefully Interrupt a Goroutine Executing (*TCPListener).Accept()?

Interrupting a Goroutine Executing (*TCPListener) Accept

When creating a server that responds to clients over a TCP connection, a go-routine is often used to handle incoming connections using (*TCPListener).Accept(). The question arises as to how to cleanly shut down the server and interrupt the goroutine blocked in this call.

The documentation for (*TCPListener).Accept() states that it waits for the next connection and returns a generic Conn. However, it provides limited information on how to interrupt this blocking operation.

The solution lies in using (TCPListener).Close(), which closes the listener and causes the goroutine executing (TCPListener).Accept() to return. This allows the server to be gracefully shut down and the go-routine to be interrupted. The go-routine should then return from the call and allow the server to exit cleanly.

The above is the detailed content of How to Gracefully Interrupt a Goroutine Executing (*TCPListener).Accept()?. For more information, please follow other related articles on the PHP Chinese website!
