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 it should work on a Mac as well, correct?
UPDATE: I fear something is still wrong here (I'm trying to avoid creating a char array with a determined length, as there's no proper way to get a decent length for getcwd):
char* a_cwd = getcwd(NULL,0);
string s_cwd(a_cwd);
free(a_cwd); // or delete a_cwd?
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();
