#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
the new #GstIterator for @list.

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().
