Would it make sense for your usage to resolve symbolic links at the same 
time?  If so, you can use the canonicalize-lgpl gnulib module, which 
portably provides the following function.

/* Return a malloc'd string containing the canonical absolute name of
    the named file.  If any file name component does not exist or is a
    symlink to a nonexistent file, return NULL.  A canonical name does
    not contain any `.', `..' components nor any repeated file name
    separators ('/') or symlinks.  */
char *canonicalize_file_name (const char *);
