as a whole. For example in the case of zip there is a comment, which
is stored at the end of the zip file. CopyArchiveMetaData() can be used
to transfer such information when writing a modified copy of an archive.
-
Since the position of the meta-data can vary between the various archive
formats, it is best to call CopyArchiveMetaData() before transferring
the entries. The wxArchiveOutputStream
will then hold on to the meta-data and write it at the correct point in
the output file.
-
When the input archive is being read from a non-seekable stream, the
meta-data may not be available when CopyArchiveMetaData() is called,
in which case the two streams set up a link and transfer the data
bool CopyArchiveMetaData(wxArchiveInputStream& stream);

and its contents copied to this stream.
-
For archive types which compress entry data, CopyEntry() is likely to be
much more efficient than transferring the data using Read() and Write()
since it will copy them without decompressing and recompressing them.
