No, that's the point of a global. Inheritance and all doesn't matter.
You change main.c (2 lines):
char* progname = 0;
...
progname = argv[0];
main.h (1 line):
extern char* progname;
and the source file where you want to use it it (2 lines):
#include "main.h"
...
printf("progname is %s\n", progname);
Your details might vary, for example if there is already a globals.h
you could move the declaration from main.h to there, etc. But this
really is the sane way of doing this...
