Building a C Application on Any Development Platform

A C sample application, based on the Consolidated Credit Services (CCSDemo) mainframe application, is included in the AppConn C API installation; however, all the principles and methodology described in the sample application are equally applicable to any other host application.

The sample application, called CCSTutor, performs the following operations:

• Allows the user to connect to the server.
• Allows the user to login to the host.
• Provides the user with the ability to look up customers by their account number or name to review their account information.

For Windows, the complete source code of CCSTutor can be found in the <VHI install folder>\examples\C-Sample folder. For UNIX, the complete source code of CCSTutor can be found in the /usr/local/vhi/examples/C-Sample directory. Use the command line to open the project called CCSTutor.cpp.
