Input Parameters

Name	Type	Description
n	const MKL_INT	Size of the array `ibuf`
ibuf	const unsigned int	Array of `n` 32-bit integers
icallback		Pointer to the callback function used for `ibuf` update

Note

Format of the callback function:

int iUpdateFunc( VSLStreamStatePtr stream, int* n, unsigned int ibuf[], int* nmin, int* nmax, int* idx );

The callback function returns the number of elements in the array actually updated by the function.Table icallback Callback Function Parameters gives the description of the callback function parameters.

icallback Callback Function Parameters
Parameters	Short Description
stream	Abstract random stream descriptor
n	Size of `ibuf`
ibuf	Array of random numbers associated with the stream `stream`
nmin	Minimal quantity of numbers to update
nmax	Maximal quantity of numbers that can be updated
idx	Position in cyclic buffer `ibuf` to start update `0≤idx<n`.

Output Parameters

Name	Type	Description
stream	VSLStreamStatePtr*	Descriptor of the stream state structure

Description

The vsliNewAbstractStream function creates a new abstract stream and associates it with an integer array ibuf and your callback function icallback that is intended for updating of ibuf content.

Return Values

VSL_ERROR_OK, VSL_STATUS_OK: Indicates no error, execution is successful.
VSL_ERROR_BADARGS: Parameter n is not positive.
VSL_ERROR_MEM_FAILURE: System cannot allocate memory for stream.
VSL_ERROR_NULL_PTR: Either buffer or callback function parameter is a NULL pointer.
