program data folder, cross platform

Hi Experts,

What's the best way to get the following folders in a cross-platform manner?  (preferably using boost)?

- program data
- user home
- user roaming folder

Thanks,
Mike

Unfortunately, there is not really a common way to do that. E.g. there's no such equivalent to 'Program Data' on neither Linux or OS X, nor is there a 'roaming folder'. The most common denominator is probably using environment variables for that purpose, with 'USERPROFILE' representing the 'Home' directory on Window and 'HOME' the one on Linux/OS X. E.g. like

#include <stdlib.h>
#ifdef _WIN32
#define HOMEDIR "USERPROFILE"
#else
#define HOMEDIR "HOME"
#endif

// ...

char* HomePath = getenv(HOMEDIR);

Open in new window
