Parses a string containing a [GtkBuilder UI definition][BUILDER-UI] and merges it with the current contents of builder.
Most users will probably want to use Builder.newFromString.
Upon errors 0 will be returned and error will be assigned a GError from the GTK_BUILDER_ERROR, G_MARKUP_ERROR or G_VARIANT_PARSE_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 string to parse
A positive value on success, 0 if an error occurred
GException on failure.
