* Identities
|
|
* ----------
|

*
|
|
* All series start with 1, to allow 0 to be an array terminator.
|
|
* For any FUNC identity, we also provide a function signature typedef
|
|
* and a static inline function to extract a function pointer from a
|
|
* OSSL_DISPATCH element in a type safe manner.
|
|
*
|
|
* Names:
|
|
* for any function base name 'foo' (uppercase form 'FOO'), we will have
|
|
* the following:
|
|
* - a macro for the identity with the name OSSL_FUNC_'FOO' or derivates
|
|
* thereof (to be specified further down)
|
|
* - a function signature typedef with the name OSSL_'foo'_fn
|
|
* - a function pointer extractor function with the name OSSL_'foo'
|
|

/*
|

* Helper macro to create the function signature typedef and the extractor
|
|
* |type| is the return-type of the function, |name| is the name of the
