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

You cannot call getcwd with a NULL buffer. As per the Opengroup:

If buf is a null pointer, the behavior of getcwd() is unspecified.

Also, getcwd can return NULL which can break a string constructor.

You'll need to change that to something like:

char buffer[SIZE];
char *answer = getcwd(buffer, sizeof(buffer));
string s_cwd;
if (answer)
{
    s_cwd = answer;
}
