8268 * \param name method specification to surface to the managed world
8269 * \param method pointer to a C method to invoke when the method is called
8270 *
8271 * This method surfaces the C function pointed by \p method as a method
8272 * that has been surfaced in managed code with the method specified in
8273 * \p name as an internal call.
8274 *
8275 * Internal calls are surfaced to all app domains loaded and they are
8276 * accessibly by a type with the specified name.
8277 *
8278 * You must provide a fully qualified type name, that is namespaces
8279 * and type name, followed by a colon and the method name, with an
8280 * optional signature to bind.
8281 *
8282 * For example, the following are all valid declarations:
8283 *
8284 * \c MyApp.Services.ScriptService:Accelerate
8285 *
8286 * \c MyApp.Services.ScriptService:Slowdown(int,bool)
8287 *
8288 * You use method parameters in cases where there might be more than
8289 * one surface method to managed code. That way you can register different
8290 * internal calls for different method overloads.
8291 *
8292 * The internal calls are invoked with no marshalling. This means that .NET
8293 * types like \c System.String are exposed as \c MonoString* parameters. This is
8294 * different than the way that strings are surfaced in P/Invoke.
8295 *
8296 * For more information on how the parameters are marshalled, see the
8297 * <a href="http://www.mono-project.com/docs/advanced/embedding/">Mono Embedding</a>
8298 * page.
8299 *
8300 * See the <a href="mono-api-methods.html#method-desc">Method Description</a>
8301 * reference for more information on the format of method descriptions.
