cdomain
~~~~~~~
Replacement for the sphinx c-domain.
:copyright: Copyright (C) 2016 Markus Heiser
:license: GPL Version 2, June 1991 see Linux/COPYING for details.
List of customizations:
* Add option 'name' to the "c:function:" directive. With option 'name' the
ref-name of a function can be modified. E.g.::
.. c:function:: int ioctl( int fd, int request )
:name: VIDIOC_LOG_STATUS
The func-name (e.g. ioctl) remains in the output but the ref-name changed
from 'ioctl' to 'VIDIOC_LOG_STATUS'. The function is referenced by::
* :c:func:`VIDIOC_LOG_STATUS` or
* :any:`VIDIOC_LOG_STATUS` (``:any:`` needs sphinx 1.3)
