[core] Official (de facto/de jure) API for CoAP?

[Riccardo Bernardini]

Dear all,
I am planning to write a CoAP library in Ada/SPARK [1] (why? Partly because
it is fun, partly as a tough exercise in SPARK, partly for a future project
of mine).

My question is: does it exist an official API (or a preferred one) for
CoAP?

So far

(1) I went to the "Implementation" page (
http://coap.technology/impls.html) where I saw several implementations, but
no reference to a common API. I could take inspiration from an
implementation, but which one?

(2) I searched the mail archive for "API" (
https://mailarchive.ietf.org/arch/search/?email_list=core&gbt=1&q=API ),
but browsing the "Subject" of the resulting 139 messages, I did not see
anything promising (with the exception of "Common request/response API,"
but as I understand it is related to defining a set of exceptions)


Thank you in advance for your help

The IETF does not generally decide what APIs look like. I am not aware of any standardized API although the one from Californium may be the closest you might get for a flavor.

Thank you Jim.

Yes, I know, and I also know that every now and then there is some
discussion if it should (but I do not want to re-ignite this discussion
here). However, sometimes "de facto" standard APIs emerge (e.g., BSD
socket), although CoAP is maybe too young for that.

I'll check. Thank you again.
