Introduction - If you have any usage issues, please Google them yourself
This function allocates a registration context on the specified system. A registration context contains all the information needed to
perform the MregCalculate() operation, including global registration settings and settings for each registration element.
When you allocate a registration context, it is defined with a default number of registration elements (256). You can add or remove
registration elements using MregControl() with M_NUMBER_OF_ELEMENTS.
When the registration context is no longer required, you should release its memory, using MregFree().
