The descriptor definition takes the form of a NULL terminated array of descriptor field definitions. These definitions describe how the raw descriptor data buffer should be interpreted. Thus the knowledge of how to interpret a descriptor buffer is separate from the shared code that renders the descriptor dump. This has two advantages: 1. The code for dumping descriptors is common, so the output is easy to keep consistent. It is also consistent and thorough in its handling of insufficient descriptor data buffer, and junk data at the end of a descriptor. 2. It is easy to add support for new descriptors, since they are now simple definitions that resemble the tables in the USB specifications. --- desc-dump.c | 550 ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ desc-dump.h | 64 +++++++ 2 files changed, 614 insertions(+) create mode 100644 desc-dump.c create mode 100644 desc-dump.hSame meta-comments as on patch 2 apply here :)
