BitVecFindLastPattern

Description

Find last occurrence of a bit pattern in the bitvector.

Parameters

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

Usage example (from documentation) 

  u64 index = BitVecFindLastPattern(&flags, &pattern);

Success

Index of last occurrence, or SIZE_MAX if not found

Failure

Returns SIZE_MAX when the pattern is absent or longer than bv.
