Macro Definition Documentation

ABS

#define ABS

(

x

)

( ((x)<0) ? -(x) : (x) )

Give the absolute value of x, independent of its type.

Definition at line 40 of file cmp.h.

CLAMP

#define CLAMP	(		min,
			v,
			max
	)

Value:

  ( ((v) < (min)) ? (min) :                     \
    ((v) > (max)) ? (max) :                     \
    (v) )

Definition at line 34 of file cmp.h.

MAX

#define MAX	(		a,
			b
	)		( ((a)<(b)) ? (b) : (a) )

Macros for MIN/MAX. Never use these when the arguments could have side-effects. {With GCC extensions we could probably define a safer MIN/MAX. But depending on that safety would be dangerous, since not every platform has it.}

MIN

#define MIN	(		a,
			b
	)		( ((a)>(b)) ? (b) : (a) )
