Configuration Data Structures
=============================
It is recommended that applications be configured using ``<rtems/confdefs.h>``
as it is simpler and insulates applications from changes in the underlying data
structures. However, it is sometimes important to understand the data
structures that are automatically filled in by the configuration parameters.
This section describes the primary configuration data structures.
If the user wishes to see the details of a particular data structure, they are
are advised to look at the source code. After all, that is one of the
advantages of RTEMS.
