In this case we don't need it in cache.h, it can be declared inside setup.c as static int abspath_part_inside_repo(char *dst, const char *path); (or "static inline" ) ----------------- (And not in this patch: see the final setup.c:) if (g) { free(npath); return NULL; } If this is the only caller of abspath_part_inside_repo(), then do we need npath 2 times as a parameter ? Or can we re-write it to look like this: static inline int abspath_part_inside_repo(char *path) [ ] -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
