RandG

The GRand struct is an opaque data structure. It should only be accessed through the g_rand_* functions.

Constructors

this this(GRand* gRand, bool ownedRef): Sets our main struct and passes it to the parent class.
this this(): Creates a new random number generator initialized with a seed taken either from /dev/urandom (if existing) or from the current time (as a fallback).
this this(uint seed): Creates a new random number generator initialized with seed.
this this(uint[] seed): Creates a new random number generator initialized with seed.

A destructor is present on this object, but not explicitly documented in the source.

copy RandG copy(): Copies a GRand into a new one with the same exact state as before. This way you can take a snapshot of the random number generator for replaying later.
doubleRange double doubleRange(double begin, double end): Returns the next random gdouble from rand_ equally distributed over the range [begin..end).
free void free(): Frees the memory allocated for the GRand
getRandGStruct GRand* getRandGStruct(bool transferOwnership): Get the main Gtk struct
getStruct void* getStruct(): the main Gtk struct as a void*
intRange int intRange(int begin, int end): Returns the next random gint32 from rand_ equally distributed over the range [begin..end-1].
randDouble double randDouble(): Returns the next random gdouble from rand_ equally distributed over the range [0..1).
randInt uint randInt(): Returns the next random guint32 from rand_ equally distributed over the range [0..2^32-1].
setSeed void setSeed(uint seed): Sets the seed for the random number generator GRand to seed.
setSeedArray void setSeedArray(uint* seed, uint seedLength): Initializes the random number generator by an array of longs. Array can be of arbitrary size, though only the first 624 values are taken. This function is useful if you have many low entropy seeds, or if you require more then 32 bits of actual entropy for your application.

randomDouble double randomDouble(): Returns a random gdouble equally distributed over the range [0..1).
randomDoubleRange double randomDoubleRange(double begin, double end): Returns a random gdouble equally distributed over the range [begin..end).
randomInt uint randomInt(): Return a random guint32 equally distributed over the range [0..2^32-1].
randomIntRange int randomIntRange(int begin, int end): Returns a random gint32 equally distributed over the range [begin..end-1].
randomSetSeed void randomSetSeed(uint seed): Sets the seed for the global random number generator, which is used by the g_random_* functions, to seed.
