9189 * \param name method specification to surface to the managed world
9190 * \param method pointer to a C method to invoke when the method is called
9191 *
9192 * This method surfaces the C function pointed by \p method as a method
9193 * that has been surfaced in managed code with the method specified in
9194 * \p name as an internal call.
9195 *
9196 * Internal calls are surfaced to all app domains loaded and they are
9197 * accessibly by a type with the specified name.
9198 *
9199 * You must provide a fully qualified type name, that is namespaces
9200 * and type name, followed by a colon and the method name, with an
9201 * optional signature to bind.
9202 *
9203 * For example, the following are all valid declarations:
9204 *
9205 * \c MyApp.Services.ScriptService:Accelerate
9206 *
9207 * \c MyApp.Services.ScriptService:Slowdown(int,bool)
9208 *
9209 * You use method parameters in cases where there might be more than
9210 * one surface method to managed code. That way you can register different
9211 * internal calls for different method overloads.
9212 *
9213 * The internal calls are invoked with no marshalling. This means that .NET
9214 * types like \c System.String are exposed as \c MonoString* parameters. This is
9215 * different than the way that strings are surfaced in P/Invoke.
9216 *
9217 * For more information on how the parameters are marshalled, see the
9218 * <a href="http://www.mono-project.com/docs/advanced/embedding/">Mono Embedding</a>
9219 * page.
9220 *
9221 * See the <a href="mono-api-methods.html#method-desc">Method Description</a>
9222 * reference for more information on the format of method descriptions.
