8288 * \param name method specification to surface to the managed world

8290 *
8291 * This method surfaces the C function pointed by \p method as a method
8292 * that has been surfaced in managed code with the method specified in
8293 * \p name as an internal call.
8294 *
8295 * Internal calls are surfaced to all app domains loaded and they are
8296 * accessibly by a type with the specified name.
8297 *
8298 * You must provide a fully qualified type name, that is namespaces
8299 * and type name, followed by a colon and the method name, with an
8300 * optional signature to bind.
8301 *
8302 * For example, the following are all valid declarations:
8303 *
8304 * \c MyApp.Services.ScriptService:Accelerate
8305 *
8306 * \c MyApp.Services.ScriptService:Slowdown(int,bool)
8307 *
8308 * You use method parameters in cases where there might be more than
8309 * one surface method to managed code. That way you can register different
8310 * internal calls for different method overloads.
8311 *
8312 * The internal calls are invoked with no marshalling. This means that .NET
8313 * types like \c System.String are exposed as \c MonoString* parameters. This is
8314 * different than the way that strings are surfaced in P/Invoke.
8315 *
8316 * For more information on how the parameters are marshalled, see the
8317 * <a href="http://www.mono-project.com/docs/advanced/embedding/">Mono Embedding</a>
8318 * page.
8319 *
8320 * See the <a href="mono-api-methods.html#method-desc">Method Description</a>
