7.3.5 Datapool
Header file: "DP_handler.h" and "DP_dbus_handler.h"
These header files provide utility functions to handle the data pool daemon.
7.3.5.1 Introduction
The data pool functionality of the TAF library uses the ydata daemon to provide access to common data pools.
It provides applications and processes the opportunity to define, create and delete variable lists via D-Bus
commands. In order to achieve quick response times and a good performance when working with these
variables, writing and reading will not be handled via D-Bus but by the "shared memory" mechanism.
A data pool can be generated in two different ways:

Dynamic mode: The data pool will be generated at runtime.

Static mode: The data pool is created by a user and contains 1..n data pool lists.
The used mode is determined in the ydatad configuration file.
