Need help connecting RaspberryPi3b to PC over wifi

Hi, Newbe here and am thrilled I’ve gotten this far:
I have an ESP8266 talking back and forth to my PC using: rosrun serial_python tcp
I want to use my RaspberryPi3B instead of ESP8266, but am stumped on how to do it. The ESP program, using Arduino IDE, includes the lines:

// Set the connection to rosserial socket server
nh.getHardware()->setConnection(server, serverPort);

How would I do that to the simple ros:wiki Talker.cpp example so it runs on the pi and the Listener.cpp runs on the PC?
Thanks for any help.
