Accept Connection on Socket

See more Socket/SSL/TLS Examples

Demonstrates how to create a TCP/IP socket, listen on a port, accept an incoming connection, and send a "Hello World" message to the client. Lianja

// This example will listen at port 5555 and allows for a backlog
// of 25 pending connection requests.
