Difficulties - stat struct

• The header files are accurate
• … but extremely difficult to follow
• e.g. #include <sys/stat.h> brings in 11 different files, and defines 60 typedefs
• Searching through these is painful
• Fortunately cpp to the rescue
• cpp loads all the relevant files
• … and replaces macro definitions
• … leaving less abstracted code
• … that is easier to follow
• … as all definitions in this one output file
• … and only the correct definition for this platform (e.g. for timespec)
