vg4->actionstack->get()
Get upmost element from actionstack.
SYNTAX
void *
vg4->actionstack->get(unsigned int *name_id)
FUNCTION PARAMETERS
name_id | For returning element-ID |
RETURN VALUE
Returns element-data,
which may be NULL
DESCRIPTION
Get upmost element from actionstack.
The element will not be removed.
When the actionstack is empty, the value of name_id will be set to 0.
Just checking the return value (element-data) for NULL does not suffice,
as it could be NULL when passed to vg4->actionstack->push().
