C++: execute a while loop until a key is pressed e.g. Esc?
c++, exit, multiplatform, onkeypress, while-loop
Solution
Your best bet is to create a custom "GetAsyncKeyState" function that will use #IFDEF for windows and linux to choose the appropriate GetAsyncKeyState() or equivalent.
No other way exists to achieve the desired result, the cin approach has its problems - such as the application must be in focus.
Problem
Does anyone have a snippet of code that doesn't use `windows.h` to check for a key press within a while loop. Basically this code but without having to use `windows.h` to do it. I want to use it on Linux and Windows. ``` #include <windows.h> #include <iostream> int main() { bool exit = false; while(exit == false) { if (GetAsyncKeyState(VK_ESCAPE)) { exit = true; } std::cout<<"press esc to exit! "<<std::endl; } std::cout<<"exited: "<<std::endl; return 0; } ```
