Macro Definition Documentation

MAX

#define MAX	(		x,
			y )

Value:

((x) > (y) ? (x) : (y))

MIN

#define MIN	(		x,
			y )

Value:

((x) < (y) ? (x) : (y))

swap_values

#define swap_values	(		type,
			a,
			b )

Value:

   do {              \
      type swap_register_ = (a); \
      (a) = (b);        \
      (b) = (swap_register_);    \
   } while (0)

Swap values a and b, both of type type.

This is supposed to evaluate at compile time, giving no performance hit.
