Relative path to absolute

[AlannY]

Hi there.

I'm writing a program under Linux. I need a function that convert relative path to absolute (or full path). Under Windows, I have a GetFullPathName function in WinAPI. But now, I need function for Linux (glibc may be).

Can someone help me?

P.S. Googling, googling... nothing found ;-(

yes....
you are after "realpath". ..

#include <limits.h>
#include <stdlib.h>
#include <stdio.h>
int main()
{
        char resolved_path[100];
        realpath("../../", resolved_path);
        printf("\n%s\n",resolved_path);
        return 0;
}

Another option, if you're using c++ anyway, is to use boost::filesyst em. It provides portable file system stl-like objects.
