BitVecIsSuperset
BitVecIsSupersetDescription
Check if first bitvector is a superset of the second. A bitvector is a superset if it contains all 1-bits from the other.
Parameters
| Name | Direction | Description |
|---|---|---|
bv1 | in | Potential superset bitvector |
bv2 | in | Potential subset bitvector |
Usage example (from documentation)
bool is_superset = BitVecIsSuperset(&large_set, &small_set);
