fr_value_calc_assignment_op()

int fr_value_calc_assignment_op	(	TALLOC_CTX *	ctx,
		fr_value_box_t *	dst,
		fr_token_t	op,
		fr_value_box_t const *	src
	)

Calculate DST OP SRC.

e.g. "foo += bar".

This is done by doing some sanity checks, and then just calling the "binary operation" function.

fr_value_calc_binary_op()

int fr_value_calc_binary_op	(	TALLOC_CTX *	ctx,
		fr_value_box_t *	dst,
		fr_type_t	hint,
		fr_value_box_t const *	a,
		fr_token_t	op,
		fr_value_box_t const *	b
	)

Calculate DST = A OP B.

The result is written to DST only after it has been calculated. So it's safe to pass DST as either A or B. DST should already exist.

This function should arguably not take comparison operators, but whatever. The "promote types" code is the same for all of the binary operations, so we might as well just have one function.

Apply a set of operations in order to create an output box.

		fr_value_box_t *	dst,
		fr_type_t	type,
		fr_token_t	op,
		fr_value_box_t const *	group
	)

Calculate DST = OP { A, B, C, ...

}

The result is written to DST only after it has been calculated. So it's safe to pass DST as one of the inputs. DST should already exist.

		fr_value_box_t *	dst,

		fr_value_box_t const *	src
	)

Calculate unary operations.

e.g. "foo++", or "-foo".
