Hi, Klement
The fllowing is the my plugin vapi test result. Can you explain why ? Thank you
very much!

主题: Re: 回复： why my plugin api can not generate
vapi_want_..andvapi_alloc_want... functions?
Oh, I probably see the issue. The VPP API is poorly designed and the
message types are guessed based on names.
Your want_XYZ_event message is recognized as `event' based on the
`_event' suffix. Since events are not to be allocated and sent by
client, the vapi_alloc* functions are not generated for them.
Currently, you'll have to respect the naming convention if you want the
generator to work correctly.
So, please only use _event suffix for actual events. Change the want_XYZ
messages so that they don't end with _event and everything should work
fine.
Regards,
Klement
