"""
|
|
Convert a C header or source file ``FILE_IN``, into a ReStructured Text
|
|
included via ..parsed-literal block with cross-references for the
|
|
documentation files that describe the API. It accepts an optional
|
|
``FILE_RULES`` file to describes what elements will be either ignored or
|
|
be pointed to a non-default reference type/name.
|
|
|
|
The output is written at ``FILE_OUT``.
|
|
|
|
It is capable of identifying defines, functions, structs, typedefs,
|
|
enums and enum symbols and create cross-references for all of them.
|
|
It is also capable of distinguish #define used for specifying a Linux
|
|
ioctl.
|
|
|
|
The optional ``FILE_RULES`` contains a set of rules like:
|
|
|
|
ignore ioctl VIDIOC_ENUM_FMT
|
|
replace ioctl VIDIOC_DQBUF vidioc_qbuf
|
|
replace define V4L2_EVENT_MD_FL_HAVE_FRAME_SEQ :c:type:`v4l2_event_motion_det`
