Hi all.
What is the reason enet uses unsigned int and these time overflow macros in time.h? I enet would simply use signed int, these macros would not be needed at all. For example if we have a time INT_MAX and a second one INT_MIN , 1ms later, directly after the overflow, INT_MIN-INT_MAX would result in the correct difference 1 and INT_MAX-INT_MIN in the correct difference -1. No need for the use of ENET_TIME_DIFFERENCE at all for signed int. On the other hand, if we call ENET_TIME_DIFFERENCE(a, b) with a==1 and b==2, the result is b-a -> 1, although the correct result would have been -1. If some functions need unsigned times or return unsigned times, you could simply them from/to signed int, and all would be fine. So I do not see any advantage in using unsigned int and time.h macros instead of simply use signed int. Can you tell me the reasons for the unsigned + time.h solution? Thx, Stefan.
