C++ directory "where am I" function

kev000 · 11-17-2006, 03:37 PM

Could anyone direct me on how my Linux program could know what directory it is in?

I need to write a function to return that info in c/c++. Any ideas on how I could do that?

my idea is:

char* whereami()
{
return Directory_Where_Im_At;
}

Code:

#include <unistd.h>
#include <iostream>

int main(int argc, char **argv)
{
    using namespace std;
    cout << "current working directory is " << get_current_dir_name() << endl;
    return 0;
}

The get_current_dir_name function isn't portable to non-GNU implementations of the standard C libraries. Check out the manual page for getcwd for alternatives.
