Description of progress when working with zip files

When I look in the function TZipWrite.AddDeflated(const aZipName: TFileName; Buf: pointer; Size: PtrInt;...), only the start and the end are considered.
The description is not quite correct.

/// optional TOnInfoProgress callback triggered during Zip/Unzip
// - at least at process startup and finish, and every ReportDelay ms
property OnProgress: TOnInfoProgress
  read fInfo.OnProgress write fInfo.OnProgress;

A message after ReportDelay is never triggered for the functions:

• AddDeflated(const aZipName: TFileName; Buf: pointer; Size: PtrInt; ...)

• AddStored(const aZipName: TFileName; Buf: pointer; Size: PtrInt;...)

• AddFromZip()

• Append()

For other functions only if LIBDEFLATE_MAXSIZE is exceeded.

With best regards

Yes, this is because there is no progress callback available in the in-memory process of libdeflate.

Sorry, I could not express my intention clearly enough. I have a problem with the word "every" in the description. I would have expected a formulation more like the following:

/// optional TOnInfoProgress callback triggered during Zip/Unzip
// - at least at startup and finish, and for functions that support ReportDelay [ms] for all longer-running processes
