What is the correct way to specify an argument in a while loop in C++?

Question

C++ / C#

Hello! Started learning C++. I have a question here. How to pass a global bool variable as an argument to a while loop.

bool exit = false;
while (!::exit){
//что-то
}

Error C2659.
Thanks in advance! Do not judge strictly)
