I have the unfortunate task of doing (minimal) maintenance work on two legacy applications developed in DBIII+/Clipper '87. I have full access to source and a minimal toolchain to recompile the application when needed, but I am not allowed to reimplement it from scratch due to various (mostly psychological) reasons from the main user. Anyway, while the applications work fine under XP, hardware support is becoming a chore. The user needs to replace the failing printer (an old impact HP with parallel interface) and the 486 (!) desktop where the applications are hosted. The main problem now is to

I need to determine whether a particular string is a valid IPv4 or IPv6 address literal. If I understand correctly, the correct way to do this on POSIX systems is to use inet_pton to convert it into a network address structure and see if it succeeds. Windows Vista and later have InetPton which does essentially the same thing. But as far as I can tell, Windows XP doesn't declare either of those, and I need to be able to do this correctly on XP.

If you dump a couple thousand lines a second to the console window it generally has a negative impact on the performance of the system.

Where is the bottle neck? printf etc has to go from your process with some sort of IPC to the Console window process (csrss or conhost) The console can also be shared with several processes so there is also some synchronization and buffering going on. 来源： https://stackoverflow
