The extended header data structure contains information on the current measurement status and control and is attached in front of the measurement header, which is copied to all data sets.
/* ctrl_data.h - */
/*
The structure ctrl_data contains all information
that can be generated or influenced by the program
WeraDesk in ASCII representation.
