vslCopyStreamState

Creates a copy of a random stream state.

Syntax

status = vslcopystreamstate( deststream, srcstream )

Include Files

  • mkl.fi, mkl_vsl.f90

Input Parameters

Name

Type

Description

srcstream

TYPE(VSL_STREAM_STATE), INTENT(IN)

Descriptor of the destination stream where the state of scrstream stream is copied

Output Parameters

Name

Type

Description

deststream

TYPE(VSL_STREAM_STATE), INTENT(OUT)

Descriptor of the stream with the state to be copied

Description

The vslCopyStreamState function copies a stream state from srcstream to the existing deststream stream. Both the streams should be generated by the same basic generator. An error message is generated when the index of the BRNG that produced deststream stream differs from the index of the BRNG that generated srcstream stream.

Unlike vslCopyStream function, which creates a new stream and copies both the stream state and other data from srcstream, the function vslCopyStreamState copies only srcstream stream state data to the generated deststream stream.

Return Values

VSL_ERROR_OK, VSL_STATUS_OK

Indicates no error, execution is successful.

VSL_ERROR_NULL_PTR

Either srcstream or deststream is a NULL pointer.

VSL_RNG_ERROR_BAD_STREAM

Either srcstream or deststream is not a valid random stream.

VSL_RNG_ERROR_BRNGS_INCOMPATIBLE

BRNG associated with srcstream is not compatible with BRNG associated with deststream.
