  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'
