BitVecInsertRange
BitVecInsertRangeDescription
Insert multiple bits of the same value at a specific position. All existing bits at and after the position are shifted right.
Parameters
| Name | Direction | Description |
|---|---|---|
bv | in | Bitvector to insert into |
idx | in | Position to insert at (0-based) |
count | in | Number of bits to insert |
value | in | Value for all inserted bits (true or false) |
Usage example (from documentation)
BitVecInsertRange(&flags, 2, 5, true); // Insert 5 true bits at position 2
