Sequence.lookup

Returns an iterator pointing to the position of the first item found equal to data according to cmp_func and cmp_data. If more than one item is equal, it is not guaranteed that it is the first which is returned. In that case, you can use glib.sequence_iter.SequenceIter.next and glib.sequence_iter.SequenceIter.prev to get others.

cmp_func is called with two items of the seq, and cmp_data. It should return 0 if the items are equal, a negative value if the first item comes before the second, and a positive value if the second item comes before the first.

This function will fail if the data contained in the sequence is unsorted.

Parameters

data void*

data to look up

cmpFunc glib.types.CompareDataFunc

the function used to compare items in the sequence

Return Value

Type: glib.sequence_iter.SequenceIter

an #GSequenceIter pointing to the position of the first item found equal to data according to cmp_func and cmp_data, or null if no such item exists
