How to get the absolute path for a given relative path programmatically in Linux?
As Paul mentioned, use realpath(). Please note though, that since many file systems in Linux support hard links, any given directory can have a number of different absolute paths.
Check out the realpath function.
#include <stdlib.h> #include <stdio.h> #include <linux/limits.h>int main() { char resolved_path[PATH_MAX]; realpath("../../", resolved_path); printf("\n%s\n",resolved_path); return 0; }
