GType of elements
pointer to a GMutex protecting the list.
pointer to a guint32 that is incremented when the list is changed.
pointer to the list
object owning the list
function to call on each item retrieved
ConstructionException GTK+ fails to create the object.
Create a new iterator designed for iterating list. The list you iterate is usually part of a data structure owner and is protected with lock. The iterator will use lock to retrieve the next item of the list and it will then call the item function before releasing lock again. When a concurrent update to the list is performed, usually by owner while holding lock, master_cookie will be updated. The iterator implementation will notice the update of the cookie and will return GST_ITERATOR_RESYNC to the user of the iterator in the next call to gst_iterator_next().
