In This Chapter

To provide for maximum flexibility in adding software modules, your module is dynamically loaded as a shared object at run time. The list of loadable objects (modules) is maintained in a system configuration database file called OWconfig.

By default, Calibrator Tool reads OWconfig from the /usr/openwin/server/etc directory. If it does not find the OWconfig file or the modules in it that it is looking for, it reads the OWconfig file from /etc/openwin/server/etc.

This chapter explains how to create, insert, and remove OWconfig file entries for calibration modules. The chapter also describes how the server uses the information in OWconfig entries to locate a dynamically loadable module.

OWconfig is a database for various dynamically loadable objects. It not only can contain entries for calibration but also can include entries for other extensions and X Window System modules. The guidelines in this chapter pertain specifically to modules that interact with Calibrator Tool.
