## Overview - XOM Programming

XOM API defines a general-purpose interface for use in conjunction with other application-specific APIs for OSI services, such as XDS API to directory services or X.400 Application API to electronic mail service. It presents the application programmer with a uniform information architecture based on the concept of groups, classes, and similar information objects.

This topic describes some of the basic concepts required to understand and use the XOM API effectively.

The following names refer to the complete XDS example programs, which can be found in Sample Application Programs:

· acl.c (acl.h)

· example.c (example.h)

· teldir.c

For multithreaded XDS/XOM applications, please refer to Using Threads With The XDS/XOM API. For use of the XDS/XOM convenience functions please refer to XDS/XOM Convenience Routines.
