pitrou opened a new issue, #45820: URL: https://github.com/apache/arrow/issues/45820
### Describe the enhancement requested The `CopyBitmap` variant that returns a `std::shared_ptr<Buffer>` doesn't passing a destination bit offset for the output. Accepting such an argument would allow using that function to replace the null bitmap of an existing array, without changing its offset. ### Component(s) C++ -- This is an automated message from the Apache Git Service.
