I belive this will accept wrong numbers... 
Ex:  s="0xA0XF"
     n = strtol(&s[2], &ss, 16) whil produce:
     n  = 160 (A0) and  ss = "XF"

I belive a simple change can solve that (UNTESTED):

    if(!s[2]) 
      return -1;
    n = strtol(&s[2], &ss, base);
    if(!(*ss))
      return -1;
    else
      return (double)n;
