void	check_parser_error () const
void	set_enable_exceptions (bool f)
	The C++ API uses by defaults exceptions on errors. For applications that don't work well with exceptions (there should be only few) you have the ability to turn off exceptions. The tradeoffs are that applications have to be very careful about using check_error() after calls that may result in an erroneous state.

The tradeoffs are that applications have to be very careful about using check_error() after calls that may result in an erroneous state.
