.. ref-code-block:: cpp
	:class: doxyrest-title-code-block

	:ref:`dnnl::stream<doxid-structdnnl_1_1stream>` make_stream(
		const :ref:`dnnl::engine<doxid-structdnnl_1_1engine>`& aengine,
		:ref:`threadpool_iface<doxid-structdnnl_1_1threadpool__interop_1_1threadpool__iface>`* threadpool
		)

Constructs an execution stream for the specified engine and threadpool.



.. rubric:: Parameters:

.. list-table::
	:widths: 20 80

	*
		- aengine

		- Engine to create the stream on.

	*
		- threadpool

		- Pointer to an instance of a C++ class that implements dnnl::threapdool_iface interface.



.. rubric:: Returns:

An execution stream.

Returns the pointer to a threadpool that is used by an execution stream.



.. rubric:: Parameters:

.. list-table::
	:widths: 20 80

	*
		- astream

		- An execution stream.



.. rubric:: Returns:

Output pointer to an instance of a C++ class that implements dnnl::threapdool_iface interface or NULL if the stream was created without threadpool.
