Declaration [src]
GSequenceIter*
g_sequence_lookup_iter (
GSequence* seq,
gpointer data,
GSequenceIterCompareFunc iter_cmp,
gpointer cmp_data
)
Description [src]
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
Parameters
data
-
Type:
gpointer
Data to look up.
The argument can be NULL
.The data is owned by the caller of the method. iter_cmp
-
Type:
GSequenceIterCompareFunc
The function used to compare iterators in the sequence.
cmp_data
-
Type:
gpointer
User data passed to
iter_cmp
.The argument can be NULL
.The data is owned by the caller of the method.
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 returned data is owned by the instance. |
The return value can be NULL . |
