C/C++ Code Inspection
=====================

Call Hierarchy
--------------

When viewing a c or c++ source file you can view the call hierarchy of a
function or method by issuing the command **:CCallHierarchy**.  This will open
a temporary buffer with an inversed tree view of the hierarchy of callers of
the requested function or method.

.. code-block:: c

  fun2(int)
     fun1(int)
       main()
       fun3(int)
     fun3(int)

While you are in the hierarchy tree buffer, you can jump to the call under the
cursor using one of the following key bindings:

- <cr> - open the type using the
  (:ref:`default action <g:EclimCCallHierarchyDefaultAction>`).
- E - open the type via :edit
- S - open the type via :split
- T - open the type via :tabnew
- ? - view help buffer

**:CCallHierarchy** can also be used to view the callees for a function or
method by invoking the command with a ``!``:

.. code-block:: vim

  :CCallHierarchy!

Configuration
^^^^^^^^^^^^^

:doc:`Vim Settings </vim/settings>`

.. _g\:EclimCCallHierarchyDefaultAction:

- **g:EclimCCallHierarchyDefaultAction** (defaults to 'split') -
  Determines the command used to open the file when hitting <enter> on an entry
  in the hierarchy buffer.
