  25  * For any FUNC identity, we also provide a function signature typedef
  26  * and a static inline function to extract a function pointer from a
  27  * OSSL_DISPATCH element in a type safe manner.
  28  *
  29  * Names:
  30  * for any function base name 'foo' (uppercase form 'FOO'), we will have
  31  * the following:
  32  * - a macro for the identity with the name OSSL_FUNC_'FOO' or derivates
  33  *   thereof (to be specified further down)
  34  * - a function signature typedef with the name OSSL_'foo'_fn
  35  * - a function pointer extractor function with the name OSSL_'foo'

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

  42  * for the function (that is, it is |name|'s function signature).
