Code Samples from the Text Computer Networks and Internets includes several example programs written in C. The README file included with the code in Chapter 3 describes how to compile the code examples. Chapter 3 describes an Application Program Interface (API) for building networked applications. The code for the API and several applications that use the API is included on this Web site at http://www.netbook.cs.purdue.edu/cnaiapi. Here is a list of the cover pages for the API code and examples: API code: await_contact.c make_contact.c cname_to_comp.c appname_to_appnum.c send_eof.c cnaiapi_init.c Example code: echoclient.c echoserver.c chatclient.c chatserver.c webclient.c.c webserver.c Header files: cnaiapi.h Here is a list of cover pages for the other code samples from the text client.c from section 30.6 server.c from section 30.7 CGI script that prints date and time from section 36.7 CGI script with long-term state information from section 36.10 CGI script with short-term state information from section 36.11 Java progam for clickcount applet from section 37.13 Java progam for buttons applet from section 37.14
