Define Documentation

#define GK_MKRANDOM	(		FPRFX,
			RNGT,
			VALT
	)

The generator for the rand() related routines. \ RNGT the datatype that defines the range of values over which\ random numbers will be generated\ VALT the datatype that defines the contents of the array to \ be permuted by randArrayPermute() \ FPRFX the function prefix \

#define GK_MKRANDOM_PROTO	(		FPRFX,
			RNGT,
			VALT
	)

Value:

void FPRFX ## srand(RNGT seed); \
  RNGT FPRFX ## rand(); \
  RNGT FPRFX ## randInRange(RNGT max); \
  void FPRFX ## randArrayPermute(RNGT n, VALT *p, RNGT nshuffles, int flag);\
  void FPRFX ## randArrayPermuteFine(RNGT n, VALT *p, int flag);\
