Parses a string containing a GtkBuilder
UI definition and merges it with the current contents of builder.
Most users will probably want to use gtk_builder_new_from_string().
Upon errors 0 will be returned and error will be assigned a
GError from the GTK_BUILDER_ERROR or G_MARKUP_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().
Since 2.12
