+
+openssl/core_dispatch.h
+- OpenSSL provider dispatch numbers and function types
+
+=head1 SYNOPSIS
+
+ #include <openssl/core_dispatch.h>
+
+=head1 DESCRIPTION
+
+The F<< <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:
+
+=over 4
+
+=item operation numbers
+
+These macros have the form C<OSSL_OP_I<opname>>.
+
+=item dipatch numbers
+
+These macros have the form C<OSSL_FUNC_I<opname>_I<funcname>>, where
+C<I<opname>> is the same as in the macro for the operation this
+function belongs to.
+
+=back
+
+With every dispatch number, there is an associated function type.
+
+For further information, please see the L<provider(7)>
