It works by its author having read the applicable do***ents (a C 
textbook, and the particular compiler's do***entation) and learning from 
them.  I suggest you try that, too.

There's nothing magical about it.  See the C textbook on what (unsigned 
char *) would mean, and the compiler do***entation on the meaning of 
'xdata'.  See the rest of the source code to understand where 
Scratch_Flash_Addr might be coming from.

By reading the C textbook.
