You can use password database for that. The home_dir() would look like:

static char* home_dir(const char* name)
{
  char* home = strdup(getenv("HOME") ? getenv("HOME") : "/home");

  if(!home)
    {
      struct passwd *pw = getpwnam(name);
      if (!pw)
        return NULL;
      home = pw->pw_dir;
    }

  /* strip trailing '/' */
  if(home[strlen(home) - 1] == '/')
    home[strlen(home) - 1] = 0;

  if(name[1] != '/')
  {
    /* it's not our home, pull home back to the parent dir. */
    char* p = strrchr(home, '/');
    if(p == home)
    {
      /* home was "/dir", so use /home */
      free(home);
      return strdup("/home/");
    }
    p[1] = 0;
    return home;
  }
  /* else it is our home */
  return home;
}
