 * ----------
 *
 * 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
 * function to fetch, and |args| is a parenthesized list of parameters
 * for the function (that is, it is |name|'s function signature).

	31	* the following:
	32	* - a macro for the identity with the name OSSL_FUNC_'FOO' or derivates

	34	* - a function signature typedef with the name OSSL_'foo'_fn
