How to get system environment variables using boost library?

Question

I work on windows and MacOS, I would like to get environment variables. How to get system environment variables using boost library?

Are there equivalent to System.Environment.GetEnvironmentVariable() from .Net ?

Answer 1

There's no need for Boost. Use std::getenv from <cstdlib>, which is a standard C++ function.

Answer 2

You probably want a plain c (and ++) getenv() function, it needs not to be boosted.
