7.3.2.2 Function descriptions
The following gives you a quick overview about how a function description in this document looks like:

First there is a function description (see " Function descriptions " on page 129) that contains the function
prototype and a detailed description.

The information flow (see " Function descriptions " on page 129) contains information about the input/output
parameters (operands) and the returning values (error codes).

Next there is an example code (see " Function descriptions " on page 129) that contains a little
demonstration code.
NOTE:
The examples are meant to show the principle of how to use the function and are not necessarily
compilable.
