Interrupting a Goroutine Blocked in (*TCPListener) Accept

When developing a server that responds to TCP clients, developers may encounter a situation where they need to cleanly shut down the server and interrupt a goroutine currently blocked in the (*TCPListener) Accept function. This function is responsible for waiting for the next client connection and returning a generic Conn.

However, the documentation for Accept states that it waits for the next call, which may lead to confusion on how to interrupt the blocking goroutine. The documentation also lacks comprehensive error handling information.

To address this issue, simply use the Close() method on the net.Listener object obtained from the net.Listen(...) call. This action closes the listener, interrupting the goroutine waiting in Accept. It is essential to promptly return from the executing goroutine to prevent any potential race conditions.
