8674 * This method surfaces the C function pointed by \p method as a method
8675 * that has been surfaced in managed code with the method specified in
8676 * \p name as an internal call.
8677 *
8678 * Internal calls are surfaced to all app domains loaded and they are
8679 * accessibly by a type with the specified name.
8680 *
8681 * You must provide a fully qualified type name, that is namespaces
8682 * and type name, followed by a colon and the method name, with an
8683 * optional signature to bind.
8684 *
8685 * For example, the following are all valid declarations:
8686 *
8687 * \c MyApp.Services.ScriptService:Accelerate
8688 *
8689 * \c MyApp.Services.ScriptService:Slowdown(int,bool)
8690 *
8691 * You use method parameters in cases where there might be more than
8692 * one surface method to managed code. That way you can register different
8693 * internal calls for different method overloads.
8694 *
8695 * The internal calls are invoked with no marshalling. This means that .NET
8696 * types like \c System.String are exposed as \c MonoString* parameters. This is
8697 * different than the way that strings are surfaced in P/Invoke.
8698 *
8699 * For more information on how the parameters are marshalled, see the
8700 * <a href="http://www.mono-project.com/docs/advanced/embedding/">Mono Embedding</a>
