45 | * Returning a 0 in VERILOG_ERROR is *bad*, because | |
46 | * a zero is a legitimate number to pass in for | |
47 | * get_plus_args_num. I've changed Verilog_error to | |
48 | * return a -1, which in verilog is FFFF...FFFF. The | |
49 | * user had better explicitly check the return value. | |
50 | * | |
51 | * The functions were designed inconsistent with each other. | |
52 | * They both should return status and set a value just | |
