rc_config_open

If readonly is true parsing is generally faster, because only untranslated entries and entries that match the current locale will be loaded.

Also if you pass true for readonly, xfce_rc_config will fail if resource does not reference a regular file.

It is no error if readonly is false and the file referenced by resource does not exists. In this case you'll start with a fresh config, which contains only the default group and no entries.

Parameters:

type	The resource type being opened
resource	The resource name to open
readonly	whether to open resource readonly.

Returns:

the newly created Rc object, or null on error.
