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) - - * Handle signatures of function-like macros well.
