Developing an Application

Configuring the System Image

When you develop an application, you must make sure that the instance of the ChorusOS operating system that the application will run on contains the optional components your application requires. For example, if your application uses semaphores, you must include the SEM option. See Appendix A, Optional ChorusOS Operating System Components for information about optional components of the ChorusOS operating system.

Writing an Application

The ChorusOS 5.0 Application Developer's Guide explains the following:

• General principles of developing an application that runs on the ChorusOS operating system

• Available APIs

• How to build the application

• Different ways of running the application

Tuning

When your application is written, you can create a performance profile to check for possible performance improvements. Creating a performance profile will help you to optimize the application's use of the ChorusOS operating system. See "Performance Profiling" in the ChorusOS 5.0 Application Developer's Guide and "Configuring and Tuning" in the ChorusOS 5.0 System Administrator's Guide
