========== Namespaces

[configuration.namespaces]

This section describes the oneTBB namespace conventions.

tbb Namespace

The tbb namespace contains public identifiers defined by the library that you can reference in your program.

tbb::flow Namespace

The tbb::flow namespace contains public identifiers defined by the library that you can reference in your program related to the flow graph feature. See :doc:Flow Graph <../flow_graph> for more information.

oneapi::tbb Namespace

The tbb namespace is a part of the top level oneapi namespace. Therefore, all API from the tbb namespace (incl. the tbb::flow namespace) are available in the oneapi::tbb namespace. The oneapi::tbb namespace can be considered as an alias for the tbb namespace:

.. code:: cpp

namespace oneapi { namespace tbb = ::tbb; }
