+/* miniz.c v1.14 - public domain deflate/inflate, zlib-subset, ZIP reading/writing/appending, PNG writing
+ See "unlicense" statement at the end of this file.
+ Rich Geldreich <richgel99@gmail.com>, last updated May 20, 2012
+ 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
+ 5/20/12 v1.14 - MinGW32/64 GCC 4.6.1 compiler fixes: added MZ_FORCEINLINE, #include <time.h> (thanks fermtect).
+ 5/19/12 v1.13 - From jason@cornsyrup.org and kelwert@mtu.edu - Fix mz_crc32() so it doesn't compute the wrong CRC-32's when mz_ulong is 64-bit.
+ Temporarily/locally slammed in "typedef unsigned long mz_ulong" and re-ran a randomized regression test on ~500k files.
+ Eliminated a bunch of warnings when compiling with GCC 32-bit/64.
+ Ran all examples, miniz.c, and tinfl.c through MSVC 2008's /analyze (static analysis) option and fixed all warnings (except for the silly
+ "Use of the comma-operator in a tested expression.." analysis warning, which I purposely use to work around a MSVC compiler warning).
+ Created 32-bit and 64-bit Codeblocks projects/workspace. Built and tested Linux executables. The codeblocks workspace is compatible with Linux+Win32/x64.
+ Added miniz_tester solution/project, which is a useful little app derived from LZHAM's tester app that I use as part of the regression test.
+ Ran miniz.c and tinfl.c through another series of regression testing on ~500,000 files and archives.
+ Modified example5.c so it purposely disables a bunch of high-level functionality (MINIZ_NO_STDIO, etc.). (Thanks to corysama for the MINIZ_NO_STDIO bug report.)
+ Fix ftell() usage in examples so they exit with an error on files which are too large (a limitation of the examples, not miniz itself).
+ 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:
+ 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.
+
+ * Low-level 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
+ block large enough to hold the entire file.
+
+ The low-level tdefl/tinfl API's do not make any use of dynamic memory allocation.
+
+ * Important: For best perf. be sure to customize the below macros for your target platform:
+ #define MINIZ_USE_UNALIGNED_LOADS_AND_STORES 1
+ #define MINIZ_LITTLE_ENDIAN 1
+ #define MINIZ_HAS_64BIT_REGISTERS 1

-/* miniz.c v1.14 - public domain deflate/inflate, zlib-subset, ZIP reading/writing/appending, PNG writing
- See "unlicense" statement at the end of this file.
- Rich Geldreich <richgel99@gmail.com>, last updated May 20, 2012
- 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
- 5/20/12 v1.14 - MinGW32/64 GCC 4.6.1 compiler fixes: added MZ_FORCEINLINE, #include <time.h> (thanks fermtect).
- 5/19/12 v1.13 - From jason@cornsyrup.org and kelwert@mtu.edu - Fix mz_crc32() so it doesn't compute the wrong CRC-32's when mz_ulong is 64-bit.
- Temporarily/locally slammed in "typedef unsigned long mz_ulong" and re-ran a randomized regression test on ~500k files.
- Eliminated a bunch of warnings when compiling with GCC 32-bit/64.
- Ran all examples, miniz.c, and tinfl.c through MSVC 2008's /analyze (static analysis) option and fixed all warnings (except for the silly
- "Use of the comma-operator in a tested expression.." analysis warning, which I purposely use to work around a MSVC compiler warning).
- Created 32-bit and 64-bit Codeblocks projects/workspace. Built and tested Linux executables. The codeblocks workspace is compatible with Linux+Win32/x64.
- Added miniz_tester solution/project, which is a useful little app derived from LZHAM's tester app that I use as part of the regression test.
- Ran miniz.c and tinfl.c through another series of regression testing on ~500,000 files and archives.
- Modified example5.c so it purposely disables a bunch of high-level functionality (MINIZ_NO_STDIO, etc.). (Thanks to corysama for the MINIZ_NO_STDIO bug report.)
- Fix ftell() usage in examples so they exit with an error on files which are too large (a limitation of the examples, not miniz itself).
- 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:
- 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.
-
- * Low-level 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
- block large enough to hold the entire file.
-
- The low-level tdefl/tinfl API's do not make any use of dynamic memory allocation.
-
- * Important: For best perf. be sure to customize the below macros for your target platform:
- #define MINIZ_USE_UNALIGNED_LOADS_AND_STORES 1
- #define MINIZ_LITTLE_ENDIAN 1
- #define MINIZ_HAS_64BIT_REGISTERS 1
