I tried using c:member. It won't work on LaTeX output, as it will
still put everything into a LaTeX item, with doesn't do line breaks.
Also, according to Sphinx manual at http://www.sphinx-doc.org/en/stable/domains.html
The syntax is:
.. c:member:: type name
Describes a C struct member. Example signature:
.. c:member:: PyObject* PyTypeObject.tp_bases
So, it expects <type> <member> as arguments. If the manual is right, it
would be expecting, instead, the weird syntax:
.. c:member:: int (*) (struct v4l2_subdev *sd, u8 *buf, size_t count,ssize_t *num) rx_read
With hurts my eyes.
As I guess we don't want to maintain ourselves a LaTeX output Sphinx
plugin forked from upstream, I guess that a more definitive solution
would involve overriding the parser for c:member in a way that it would
produce an output like the one in this path, while creating the proper
c domain reference for the structure member inside the C domain.
