The first time I heard about prefixing struct members was to allow tricks like this: x8664-linux-gnu/bits/stat.h 94:# define statime statim.tvsec /* Backward compatibility. */ 95:# define stmtime stmtim.tvsec 96:# define stctime stctim.tvsec Which is relatively safe thanks to the prefix.
Believe me that is not why the prefix convention was introduced.
