*
* Purpose: This code-file defines the SUA adaptation functions used by
* the SUA application for:
* - initialising the SUA layer
* - reading the SUA configuration file
* - registering a local SUA instance
* - Setting up the association with a remote SUA node
* - get info on a certain (SUA) association
* - terminate a association
* - convert Hostname(string) to SUAname(Character array)
* - convert SUAname(Character array) to Hostname(Character array)
