GLibSequencelookup_iter
since: 2.28
Declaration
GSequenceIter*
g_sequence_lookup_iter (
GSequence* seq,
gpointer data,
GSequenceIterCompareFunc iter_cmp,
gpointer cmp_data
)
Description
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.
Available since: 2.28
This method is not directly available to language bindings.
Parameters
data-
Type:
gpointerData to look up.
The argument can be NULL.The data is owned by the caller of the function. iter_cmp-
Type:
GSequenceIterCompareFuncThe function used to compare iterators in the sequence.
cmp_data-
Type:
gpointerUser data passed to
iter_cmp.The argument can be NULL.The data is owned by the caller of the function.
Return value
Type: GSequenceIter
An GSequenceIter 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.
| The data is owned by the instance. |
The return value can be NULL. |
