BitVecMatches

BitVecMatches

Description

Match bitvector against pattern with wildcards. Wildcards allow flexible pattern matching where some positions can be “any bit”.

Parameters

Name Direction Description
bv in Bitvector to match against
pattern in Pattern bitvector to match
wildcard in Wildcard bitvector (1 = wildcard position, 0 = exact match required)

Usage example (from documentation) 

  bool matches = BitVecMatches(&data, &pattern, &wildcard);

Returns

true if pattern matches with wildcards
