.. _make_edges:
``make_edges`` function template
================================
.. note::
To enable this feature, define the ``TBB_PREVIEW_FLOW_GRAPH_FEATURES`` macro to 1.
.. contents::
:local:
:depth: 1
Description
***********
The ``make_edges`` function template creates edges between a single node
and each node in a set of nodes.
There are two ways to connect nodes in a set and a single node using
``make_edges``:

API
***
Header
------
.. code:: cpp
#include <oneapi/tbb/flow_graph.h>
Syntax
------
.. code:: cpp
// node_set is an exposition-only name for the type returned from make_node_set function
template <typename NodeType, typename Node, typename... Nodes>
void make_edges(node_set<Node, Nodes...>& set, NodeType& node);
template <typename NodeType, typename Node, typename... Nodes>
void make_edges(NodeType& node, node_set<Node, Nodes...>& set);
Example
-------
The example implements the graph structure in the picture below.
.. figure:: ./Resources/make_edges_example.png
:align: center
.. literalinclude:: ./examples/make_edges_function_example.cpp
:language: c++
:start-after: /*begin_make_edges_function_example*/
:end-before: /*end_make_edges_function_example*/
