Function Documentation

kzsError kzcRandomCreate	(	const struct KzcMemoryManager *	memoryManager,
		kzS32	seed,
		struct KzcRandom **	out_random
	)

Creates a new pseudo random number generator with the given seed.

kzsError kzcRandomCreateDefault	(	const struct KzcMemoryManager *	memoryManager,
		struct KzcRandom **	out_random
	)

Creates a new pseudo random number generator with a seed based on current system time.

kzsError kzcRandomDelete ( struct KzcRandom * random )

Frees the memory allocated for the given pseudo random number generator.

struct KzcRandom kzcRandomInline ( kzS32 seed )

Returns a pseudo random number generator without allocating memory for it.

Uses the given seed.

struct KzcRandom kzcRandomInlineDefault ( void )

Returns a pseudo random number generator without allocating memory for it.

Uses a seed based on current system time.

Sets the random seed.

kzFloat kzcRandomFloat ( struct KzcRandom * random )

Returns a random float in the range [0,1[.

Returns a random integer in the range [min,max[.
