It accepts an optional 10``FILE_RULES`` file to describes what elements will be either ignored or 11be pointed to a non-default reference type/name. 12 13The output is written at ``FILE_OUT``. 14 15It is capable of identifying defines, functions, structs, typedefs, 16enums and enum symbols and create cross-references for all of them. 17It is also capable of distinguish #define used for specifying a Linux 18ioctl. 19 20The optional ``FILE_RULES`` contains a set of rules like: 21 22 ignore ioctl VIDIOC_ENUM_FMT 23 replace ioctl VIDIOC_DQBUF vidioc_qbuf 24 replace define V4L2_EVENT_MD_FL_HAVE_FRAME_SEQ :c:type:`v4l2_event_motion_det` 25""" 26 27import argparse 28 29from lib.parse_data_structs import ParseDataStructs 30from lib.enrich_formatter import EnrichFormatter 31 32def main(): 33 """Main function""" 34 parser = argparse.ArgumentParser(description=__doc__, 35 formatter_class=EnrichFormatter) 36 37 parser.add_argument("-d", "--debug", action="count", default=0, 38 help="Increase debug level.
