What is a cross-platform way to get the current directory?

Question

I need a cross-platform way to get the current working directory (yes, getcwd does what I want). I thought this might do the trick:

#ifdef _WIN32
    #includ

If it is no problem for you to include, use boost filesystem for convenient cross-platform filesystem operations.

boost::filesystem::path full_path( boost::filesystem::current_path() );

Here is an example.

EDIT: as pointed out by Roi Danton in the comments, filesystem became part of the ISO C++ in C++17, so boost is not needed anymore:

std::filesystem::current_path();
