8185 * \param name method specification to surface to the managed world
8186 * \param method pointer to a C method to invoke when the method is called
8187 *
8188 * This method surfaces the C function pointed by \p method as a method
8189 * that has been surfaced in managed code with the method specified in
8190 * \p name as an internal call.
8191 *
8192 * Internal calls are surfaced to all app domains loaded and they are
8193 * accessibly by a type with the specified name.
8194 *
8195 * You must provide a fully qualified type name, that is namespaces
8196 * and type name, followed by a colon and the method name, with an
8197 * optional signature to bind.
8198 *
8199 * For example, the following are all valid declarations:
8200 *
8201 * \c MyApp.Services.ScriptService:Accelerate
8202 *
8203 * \c MyApp.Services.ScriptService:Slowdown(int,bool)
8204 *
8205 * You use method parameters in cases where there might be more than
8206 * one surface method to managed code. That way you can register different
8207 * internal calls for different method overloads.
8208 *
8209 * The internal calls are invoked with no marshalling. This means that .NET
8210 * types like \c System.String are exposed as \c MonoString* parameters. This is
8211 * different than the way that strings are surfaced in P/Invoke.
8212 *
8213 * For more information on how the parameters are marshalled, see the
8214 * <a href="http://www.mono-project.com/docs/advanced/embedding/">Mono Embedding</a>
8215 * page.
8216 *
8217 * See the <a href="mono-api-methods.html#method-desc">Method Description</a>
8218 * reference for more information on the format of method descriptions.
