ucase_tcp

---

The following are a server and client program that demonstrate TCP sockets. The client reads a line of text from stdin and sends this line to the server; the server than capitalizes the line and sends it back to the client, who prints this line. Once the user hits CTRL-d, the client closes its connection.

• server: ucase_tcp_server.c
• client: ucase_tcp_client.c
• common: common.h, common.c
• Implements read_line, which both the server and client use to read a line of data from a socket.
• mu: mu.h, mu.c
• mu_init_sockaddr_in: initialize a struct sockaddr_in from a string IPv4 address and string port number.
• mu_reusaddr: set the SO_REUSEADDR on a server's TCP socket so that we can immediately re-start the program and re-bind to the same socket in the event that the server crashes or otherwise abruptly stops.
