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.
If you are simply searching for an existing element of the sequence,
consider using Sequence.lookupIter.
This function will fail if the data contained in the sequence is
unsorted.
Like Sequence.search, but uses a GSequenceIterCompareFunc instead of a GCompareDataFunc as the compare function.
