Gets the current value that iter points to.
If iter is not valid and [methodGtk.BitsetIter.is_valid]
returns %FALSE, this function returns 0.
Checks if iter points to a valid value.
Moves iter to the next value in the set.
If it was already pointing to the last value in the set,
%FALSE is returned and iter is invalidated.
Moves iter to the previous value in the set.
If it was already pointing to the first value in the set,
%FALSE is returned and iter is invalidated.
Initializes iter to point to target.
If target is not found, finds the next value after it.
If no value >= target exists in set, this function returns %FALSE.
a GtkBitset
target value to start iterating at
Initializes an iterator for set and points it to the first
value in set.
If set is empty, %FALSE is returned and value is set to %G_MAXUINT.
a GtkBitset
Initializes an iterator for set and points it to the last
value in set.
If set is empty, %FALSE is returned.
a GtkBitset
An opaque, stack-allocated struct for iterating over the elements of a
GtkBitset.Before a
GtkBitsetItercan be used, it needs to be initialized with [funcGtk.BitsetIter.init_first], [funcGtk.BitsetIter.init_last] or [funcGtk.BitsetIter.init_at].
