Like Sequence.lookup, but uses a GSequenceIterCompareFunc instead of a GCompareDataFunc as the compare function.

iter_cmp is called with two iterators pointing into seq. It should return 0 if the iterators are equal, a negative value if the first iterator comes before the second, and a positive value if the second iterator comes before the first.

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

class Sequence


data void*

data to look up

iterCmp GSequenceIterCompareFunc

the function used to compare iterators in the sequence

cmpData void*

user data passed to iter_cmp

Return Value

an glib.SequenceIter pointing to the position of the first item found equal to data according to iter_cmp and cmp_data, or NULL if no such item exists
