8107 * \param name method specification to surface to the managed world
8108 * \param method pointer to a C method to invoke when the method is called
8109 *
8110 * This method surfaces the C function pointed by \p method as a method
8111 * that has been surfaced in managed code with the method specified in
8112 * \p name as an internal call.
8113 *
8114 * Internal calls are surfaced to all app domains loaded and they are
8115 * accessibly by a type with the specified name.
8116 *
8117 * You must provide a fully qualified type name, that is namespaces
8118 * and type name, followed by a colon and the method name, with an
8119 * optional signature to bind.
8120 *
8121 * For example, the following are all valid declarations:
8122 *
8123 * \c MyApp.Services.ScriptService:Accelerate
8124 *
8125 * \c MyApp.Services.ScriptService:Slowdown(int,bool)
8126 *
8127 * You use method parameters in cases where there might be more than
8128 * one surface method to managed code. That way you can register different
8129 * internal calls for different method overloads.
8130 *
8131 * The internal calls are invoked with no marshalling. This means that .NET
8132 * types like \c System.String are exposed as \c MonoString* parameters. This is
8133 * different than the way that strings are surfaced in P/Invoke.
8134 *
8135 * For more information on how the parameters are marshalled, see the
8136 * <a href="http://www.mono-project.com/docs/advanced/embedding/">Mono Embedding</a>
8137 * page.
8138 *
8139 * See the <a href="mono-api-methods.html#method-desc">Method Description</a>
8140 * reference for more information on the format of method descriptions.
