* pyg_flags_get_value:

* @obj: a Python object representing the flag value
* @val: a pointer to the location to store the integer representation of the flag.
*
* Converts a Python object to the integer equivalent. The conversion
* will depend on the type of the Python object. If the object is an
* integer, it is passed through directly. If it is a string, it will
* be treated as a full or short flag name as defined in the GType.
