BitVecCountPattern

Description

Count total occurrences of a bit pattern in the bitvector.

Parameters

Name Direction Description
bv in Bitvector to search in
pattern in Pattern to count

Usage example (from documentation) 

  u64 count = BitVecCountPattern(&flags, &pattern);

Success

Number of occurrences found

Failure

Returns 0 when the pattern never matches or is longer than bv.
