8129 * mono_add_internal_call:
8130 * \param name method specification to surface to the managed world
8131 * \param method pointer to a C method to invoke when the method is called
8132 *
8133 * This method surfaces the C function pointed by \p method as a method
8134 * that has been surfaced in managed code with the method specified in
8135 * \p name as an internal call.
8136 *
8137 * Internal calls are surfaced to all app domains loaded and they are
8138 * accessibly by a type with the specified name.
8139 *
8140 * You must provide a fully qualified type name, that is namespaces
8141 * and type name, followed by a colon and the method name, with an
8142 * optional signature to bind.
8143 *
8144 * For example, the following are all valid declarations:
8145 *
8146 * \c MyApp.Services.ScriptService:Accelerate
8147 *
8148 * \c MyApp.Services.ScriptService:Slowdown(int,bool)
8149 *
8150 * You use method parameters in cases where there might be more than
8151 * one surface method to managed code. That way you can register different
8152 * internal calls for different method overloads.
8153 *
8154 * The internal calls are invoked with no marshalling. This means that .NET
8155 * types like \c System.String are exposed as \c MonoString* parameters. This is
8156 * different than the way that strings are surfaced in P/Invoke.
8157 *
8158 * For more information on how the parameters are marshalled, see the
8159 * <a href="http://www.mono-project.com/docs/advanced/embedding/">Mono Embedding</a>
8160 * page.
8161 *
8162 * See the <a href="mono-api-methods.html#method-desc">Method Description</a>
8163 * reference for more information on the format of method descriptions.
