Detailed Description

Functions to create, modify, use, and destroy randomEngine objects.

A af::randomEngine object can be used to generate psuedo random numbers using various types of random number generation algorithms defined by af::randomEngineType.

Function Documentation

◆ af_create_random_engine()

AFAPI af_err af_create_random_engine	(	af_random_engine *	engine,
		af_random_engine_type	rtype,
		unsigned long long	seed
	)

C Interface to create a random engine.

Parameters

[out]	engine	pointer to the returned random engine object
[in]	rtype	type of the random number generator
[in]	seed	initializing seed of the random number generator

Returns: AF_SUCCESS, if function returns successfully, else an af_err code is given

◆ af_random_engine_get_seed()

AFAPI af_err af_random_engine_get_seed	(	unsigned long long *const	seed,
		af_random_engine	engine
	)

C Interface to get the seed of a random engine.

Parameters

[out]	seed	pointer to the returned seed
[in]	engine	random engine object

Returns: AF_SUCCESS, if function returns successfully, else an af_err code is given

◆ af_random_engine_get_type()

AFAPI af_err af_random_engine_get_type	(	af_random_engine_type *	rtype,
		const af_random_engine	engine
	)

C Interface to get random engine type.

Parameters

[out]	rtype	type of the random number generator
[in]	engine	random engine object

Returns: AF_SUCCESS, if function returns successfully, else an af_err code is given

AFAPI af_err af_random_engine_set_seed	(	af_random_engine *	engine,
		const unsigned long long	seed
	)

C Interface to set the seed of a random engine.

Parameters

[out]	engine	pointer to the returned random engine object
[in]	seed	initializing seed of the random number generator

Returns: AF_SUCCESS, if function returns successfully, else an af_err code is given

◆ af_random_engine_set_type()
