but there is no uint16_t involved here.

What if someone has already registered 7e/7f ?
Doing the find (setting the booleans) and message construction (setting msg_types) in the same place is a bit unusual.
If you're taking the approach that 7e/7f do not appear in the supported_message_types array, then I would suggest detecting their presence earlier (ie, iterating supported_vdm_types there), which means you can then allocate exactly the correct size message, then do the message construction later, based on the earlier detection.

I think 7e or 7f can come in supported_message_types .

might be good to also test that the type is removed after unregistration, but you could also do that in the original unregistration test.

Removed the newly added test. Updated VDM test

If VDM type support is registered using dbus call RegisterVDMTypeSupport then add 7E and 7F based on the format in GetMsgType control command response Signed-off-by: Nidhin MS <[email protected]>
