My code of getting pick event is as follows:

    while (1) {
	pawait_event(0.0, &ws, &class, &dev);
	if (class == PIN_PICK) {
	    pget_pick(PATHDEPTH, &status, &path);
	    if (status == PIN_STATUS_OK) {
		if (path.path_list[1].struct_id == 1)	puts("1");
		else					puts("2");
	    }
	    else					puts("nothing");
	}
    }

This code runs correctly at the first pick, but then it can get pick
event (class == PIN_PICK) without the information (status !=
PIN_STATUS_OK and path.path_list is unchanged).
