`BitVecFindAllPattern`

Description

Find all occurrences of a bit pattern in the bitvector. Results array must be pre-allocated with sufficient space.

Parameters

Name	Direction	Description
`bv`	in	Bitvector to search in
`pattern`	in	Pattern to search for
`results`	out	Array to store found indices
`max_results`	in	Maximum number of results to store

Usage example (from documentation)

  u64 indices[10];
  u64 count = BitVecFindAllPattern(&flags, &pattern, indices, 10);
