BitVecRemoveRange
BitVecRemoveRangeDescription
Remove multiple consecutive bits starting at a specific position. All bits after the removed range are shifted left.
Parameters
| Name | Direction | Description |
|---|---|---|
bv | in | Bitvector to remove from |
idx | in | Starting position (0-based) |
count | in | Number of bits to remove |
Usage example (from documentation)
BitVecRemoveRange(&flags, 2, 3); // Remove 3 bits starting at position 2
