To deal with this warning in Mac:
warning: passing an object that undergoes default argument promotion to 'va_start' has undefined behavior [-Wvarargs] va_start( print_params, warning );,change
bool warningtoint warning.Concerning va_list and the ellipsis, the rightmost argument and all unnamed ones are subjects for default argument promotion. If a real argument’s type is char, short (with or without a sign) or float (in the above case, a bool), the corresponding parameter must be treated as int, int (with or without a sign) or double.
Otherwise – undefined behavior [C11 7.16.1.1./2].
