Has anybody thought about replacing #defines with enums in header
files? It would make debugging a whole lot easier. Foe example, I'm
currently looking at a debug printout which contains:
xerrno = 17,
To find out what that means, I need to go to
/usr/src/include/sys/errno.h and look for 17. I find:
#define EEXIST 17 /* File exists */
If we were to change this to
enum EEXIST = 17; /* File exists */
I'd then be able to see:
xerrno = EEXIST,
That makes debugging a whole lot easier. About the only down side I
can see is that you can't #undef an enum. Is this a big deal?
