Openssl provider dispatch numbers and function types

Usage

 #include <openssl/core_dispatch.h>

Overview

The <openssl/core_dispatch.h> header defines all the operation numbers, dispatch numbers and provider interface function types currently available.

The operation and dispatch numbers are represented with macros, which are named as follows:

operation numbers

These macros have the form "OSSL_OP_opname".

dispatch numbers

These macros have the form "OSSL_FUNC_opname_funcname", where "opname" is the same as in the macro for the operation this function belongs to.

With every dispatch number, there is an associated function type.
