Parses a resource file containing a [GtkBuilder UI definition][BUILDER-UI] and merges it with the current contents of @builder.
Most users will probably want to use gtk_builder_new_from_resource().
If an error occurs, 0 will be returned and @error will be assigned a #GError from the #GTK_BUILDER_ERROR, #G_MARKUP_ERROR or #G_RESOURCE_ERROR domain.
It’s not really reasonable to attempt to handle failures of this call. The only reasonable thing to do when an error is detected is to call g_error().
the path of the resource file to parse
A positive value on success, 0 if an error occurred
GException on failure.
