JUDGE_AVAILABLE

#define JUDGE_AVAILABLE	(		x,
			minimum,
			maximum
	)

Value:

                                                    if (x > maximum || x < minimum) \
                                                    x = 0

determine whether the read-out variable is within the trusted range

Parameters

[in]	x	variables to be judged
[in]	minimum	the minimum value of this variable
