gtk:bitset-iter-init-at (iter bitset target)

iter -- an uninitialized gtk:bitset-iter instance
bitset -- a gtk:bitset instance
target -- an unsigned integer with the target value to start iterating at

The unsigned integer with the found value in bitset, or nil.

Initializes an iterator for the bitset to point to target. If target is not found, finds the next value after it. If no value greater than or equal target exists in the bitset, this function returns nil.
