BitVecRegexMatch
BitVecRegexMatchDescription
Simple regex-style pattern matching for bitvectors. Supports basic patterns: ‘*’ (any sequence), ‘?’ (0 or 1), ‘[01]’ (literal).
Parameters
| Name | Direction | Description |
|---|---|---|
bv | in | Bitvector to match against |
pattern | in | Pattern string using regex syntax |
Usage example (from documentation)
bool matches = BitVecRegexMatch(&data, "10*01"); // 10 followed by any bits, then 01
