function lookup(name:String):Boolean {
    // Gjs wrapper for gst_child_proxy_lookup()
}

Looks up which object and GObject.ParamSpec would be effected by the given name.

MT safe.

name: name of the property to look up
Returns: TRUE if target and pspec could be found. FALSE otherwise. In that case the values for pspec and target are not modified. Unref target after usage. For plain GObjects target is the same as object.
