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
    #include <direct.h>
    #define getcwd _getcwd // stupid MSFT "deprecation" warning
#elif
    #include <unistd.h>
#endif
#include <string>
#include <iostream>
using namespace std;

int main()
{
    string s_cwd(getcwd(NULL,0));
    cout << "CWD is: " << s_cwd << endl;
}

I got this reading:

There should be no memory leaks, and is should work on a Mac as well, correct?
