Method   Gio  Conditions list   ================================================


−>  Declaration   --------------------------------------------------------------

gchar** g_conditions_list (GConditions* conditions)

−>   Description   -------------------------------------------------------------

Gets the list of conditions.
The list is the list of strings for which it is not an error to call g_conditions_get().
There is little reason to call this function from “normal” code,
  since you should already know what conditions are in your schema.
  This function may still be useful there for introspection reasons, however.
You should free the return value with g_strfreev() when you are done with it.


−>   Return value   ------------------------------------------------------------

Type: An array of utf8
A list of the conditions values and parents, in no defined order.
The array is NULL-terminated.
The caller of the method takes ownership of the data,
                         and is responsible for freeing it.
Each element is a NUL terminated UTF-8 string.
