 * atk_plug_get_id:

 * @plug: an #AtkPlug

 *

 * Gets the unique ID of an #AtkPlug object, which can be used to

 * embed inside of an #AtkSocket using atk_socket_embed().

 *

 * Internally, this calls a class function that should be registered

 * by the IPC layer (usually at-spi2-atk). The implementor of an

 * #AtkPlug object should call this function (after atk-bridge is

 * loaded) and pass the value to the process implementing the

 * #AtkSocket, so it could embed the plug.

 *

 * Returns: the unique ID for the plug

 *

 * Since: 1.30
