GLibSequencelookup_iter

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: gpointerData to look up. The argument can be NULL.The data is owned by the caller of the method. 
- 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 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. |
