Sequence.lookupIter

Like g_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
lookupIter

Parameters

data void*

data to lookup

iterCmp GSequenceIterCompareFunc

the function used to compare iterators in the sequence

cmpData void*

user data passed to @iter_cmp

Return Value

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
