- gzappend takes a gzip file and appends to it, compressing files from the
- command line or data from stdin. The gzip file is written to directly, to
- avoid copying that file, in case it's large. Note that this results in the
- unfriendly behavior that if gzappend fails, the gzip file is corrupted.
-
- This program was written to illustrate the use of the new Z_BLOCK option of
- zlib 1.2.1's inflate() function. This option returns from inflate() at each
- block boundary to facilitate locating and modifying the last block bit at
- the start of the final deflate block. Also whether using Z_BLOCK or not,
- another required feature of zlib 1.2.1 is that inflate() now provides the
- number of unusued bits in the last input byte used. gzappend will not work
- with versions of zlib earlier than 1.2.1.
-
- gzappend first decompresses the gzip file internally, discarding all but
- the last 32K of uncompressed data, and noting the location of the last block
- bit and the number of unused bits in the last byte of the compressed data.
- The gzip trailer containing the CRC-32 and length of the uncompressed data
- is verified. This trailer will be later overwritten.
-
- Then the last block bit is cleared by seeking back in the file and rewriting
- the byte that contains it. Seeking forward, the last byte of the compressed
- data is saved along with the number of unused bits to initialize deflate.
-
- A deflate process is initialized, using the last 32K of the uncompressed
- data from the gzip file to initialize the dictionary. If the total
- uncompressed data was less than 32K, then all of it is used to initialize
- the dictionary. The deflate output bit buffer is also initialized with the
- last bits from the original deflate stream. From here on, the data to
- append is simply compressed using deflate, and written to the gzip file.
- When that is complete, the new CRC-32 and uncompressed length are written
- as the trailer of the gzip file.

-See below some functions declarations for Visual Basic.

-Frequently Asked Question:
-
-Q: Each time I use the compress function I get the -5 error (not enough
- room in the output buffer).
-
-A: Make sure that the length of the compressed buffer is passed by
- reference ("as any"), not by value ("as long"). Also check that
- before the call of compress this length is equal to the total size of
- the compressed buffer and not zero.

-Here is another example from Michael <michael_borgsys@hotmail.com> that he
-says conforms to the VB guidelines, and that solves the problem of not
-knowing the uncompressed size by storing it at the end of the file:
-

-'bracket meaning: <parameter> [optional] {Range of possible values}
-'Call subCompressFile(<path with filename to compress> [, <path with
-filename to write to>, [level of compression {1..9}]])
-'Call subUncompressFile(<path with filename to compress>)
-

-Private Const strFilExt As String = ".cpr"
