It is used when recreting zip archive with RAW when deleting items from a zip.
It is used when recreating zip archive with RAW when deleting items from a zip.
ZIP64 data is automatically added to items that needs it, and existing ZIP64 data need to be removed.

We start off by reading data from the input file. The number of bytes read is put directly
into <tt>avail_in</tt>, and a pointer to those bytes is put into <tt>next_in</tt>. We also
check to see if end-of-file on the input has been reached. If we are at the end of file, then <tt>flush</tt> is set to the
check to see if end-of-file on the input has been reached using feof().
If we are at the end of file, then <tt>flush</tt> is set to the
<em>zlib</em> constant <tt>Z_FINISH</tt>, which is later passed to <tt>deflate()</tt> to
indicate that this is the last chunk of input data to compress. We need to use <tt>feof()</tt>
to check for end-of-file as opposed to seeing if fewer than <tt>CHUNK</tt> bytes have been read. The
reason is that if the input file length is an exact multiple of <tt>CHUNK</tt>, we will miss
the fact that we got to the end-of-file, and not know to tell <tt>deflate()</tt> to finish
up the compressed stream. If we are not yet at the end of the input, then the <em>zlib</em>
indicate that this is the last chunk of input data to compress.
If we are not yet at the end of the input, then the <em>zlib</em>
constant <tt>Z_NO_FLUSH</tt> will be passed to <tt>deflate</tt> to indicate that we are still

/* Illustrate the use of Z_BLOCK, inflatePrime(), and inflateSetDictionary()
for random access of a compressed file. A file containing a zlib or gzip
stream is provided on the command line. The compressed stream is decoded in
its entirety, and an index built with access points about every SPAN bytes
in the uncompressed output. The compressed file is left open, and can then
be read randomly, having to decompress on the average SPAN/2 uncompressed
bytes before getting to the desired block of data.
An access point can be created at the start of any deflate block, by saving
the starting file offset and bit of that block, and the 32K bytes of
uncompressed data that precede that block. Also the uncompressed offset of
that block is saved to provide a reference for locating a desired starting
point in the uncompressed stream. deflate_index_build() works by
decompressing the input zlib or gzip stream a block at a time, and at the
end of each block deciding if enough uncompressed data has gone by to
justify the creation of a new access point. If so, that point is saved in a
data structure that grows as needed to accommodate the points.
To use the index, an offset in the uncompressed data is provided, for which
the latest access point at or preceding that offset is located in the index.
The input file is positioned to the specified location in the index, and if
necessary the first few bits of the compressed data is read from the file.
inflate is initialized with those bits and the 32K of uncompressed data, and
the decompression then proceeds until the desired offset in the file is
reached. Then the decompression continues to read the desired uncompressed
data from the file.
Another approach would be to generate the index on demand. In that case,
requests for random access reads from the compressed data would try to use
the index, but if a read far enough past the end of the index is required,
then further index entries would be generated and added.
There is some fair bit of overhead to starting inflation for the random
access, mainly copying the 32K byte dictionary. So if small pieces of the
file are being accessed, it would make sense to implement a cache to hold
some lookahead and avoid many calls to deflate_index_extract() for small
lengths.
Another way to build an index would be to use inflateCopy(). That would
not be constrained to have access points at block boundaries, but requires
more memory per access point, and also cannot be saved to file due to the
use of pointers in the state. The approach here allows for storage of the
index in a file.
