// example5.c - Demonstrates how to use miniz.c's low-level tdefl_compress() and tinfl_inflate() API's for simple file to file compression/decompression.

Implements RFC 1950: http://www.ietf.org/rfc/rfc1950.txt and RFC 1951: http://www.ietf.org/rfc/rfc1951.txt
Most API's defined in miniz.c are optional. For example, to disable the archive related functions just define
MINIZ_NO_ARCHIVE_APIS, or to get rid of all stdio usage define MINIZ_NO_STDIO (see the list below for more macros).
* Change History
4/12/12 v1.12 - More comments, added low-level example5.c, fixed a couple minor level_and_flags issues in the archive API's.
level_and_flags can now be set to MZ_DEFAULT_COMPRESSION. Thanks to Bruce Dawson <bruced@valvesoftware.com> for the feedback/bug report.
5/28/11 v1.11 - Added statement from unlicense.org
5/27/11 v1.10 - Substantial compressor optimizations:
May 15, v1.09 - Initial stable release.
May 27, v1.10 - Substantial compressor optimizations:
Level 1 is now ~4x faster than before. The L1 compressor's throughput now varies between 70-110MB/sec. on a
Core i7 (actual throughput varies depending on the type of data, and x64 vs. x86).
Improved baseline L2-L9 compression perf. Also, greatly improved compression perf. issues on some file types.
Refactored the compression code for better readability and maintainability.
Added level 10 compression level (L10 has slightly better ratio than level 9, but could have a potentially large
drop in throughput on some files).
5/15/11 v1.09 - Initial stable release.
May 28, v1.11 - Added statement from unlicense.org
* Low-level Deflate/Inflate implementation notes:
* Deflate/Inflate implementation notes:
Compression: Use the "tdefl" API's. The compressor supports raw, static, and dynamic blocks, lazy or
greedy parsing, match length filtering, RLE-only, and Huffman-only streams. It performs and compresses
approximately as well as zlib.
Decompression: Use the "tinfl" API's. The entire decompressor is implemented as a single function
coroutine: see tinfl_decompress(). It supports decompression into a 32KB (or larger power of 2) wrapping buffer, or into a memory
coroutine: see tinfl_decompress(). It supports decompression into a 32KB wrapping buffer or into a memory
block large enough to hold the entire file.
The low-level tdefl/tinfl API's do not make any use of dynamic memory allocation.
