c++ - Programmatic way to see if a PC is connected to a specified network -

-

os: windows, language: c++

i'm implementing use case: when user starts software, software needs know if his/her pc connected specified network (e.g. college campus intranet). if yes, of software's features enabled.

i'm new area , cannot tell reliable programmatic way. function getcomputernameex (https://msdn.microsoft.com/en-us/library/windows/desktop/ms724301%28v=vs.85%29.aspx) seems promising. if function works use case, data obtained function can rely on?

thanks in advance!

one of more reliable indicators presence of mac addresses: these visible inside lan, not on global internet. on nat'ted ipv4 networks mac address globally unique.

on windows can try sendarp

[C++][SFML 2.2] Strange Performance Issues - Moving Mouse Lowers CPU Usage -

-
i've been working on making 2d map editor past 2 weeks or so, , i've run strange problem. trying optimize code, example, making functions should've been functions begin with, did made cpu usage go through roof. i've tried commenting out different sections of code thought culprits (scrolling, rendering, other calculations) no avail. think issue might trying call things within different functions, sake of making modular possible, i'd functionality. the other major change i've made since file i'm comparing i've ported variables external cpp file, since having variables global makes lot easier use within different functions. simple issue, can't life of me understand why happens. with original code, around 2-3% cpu usage. new code, around 20-35%, but, if move mouse around, it'll drop around 6-8%. tl;dr: after trying optimize code using functions, i've somehow killed performance, , found strange quirk moving mouse reduces cpu usage.. /...
