-/* miniz.c 3.0.2 - 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 Oct. 13, 2013 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).
-
- * 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.
-
- * zlib-style API notes:
-
- miniz.c implements a fairly large subset of zlib. There's enough
- functionality present for it to be a drop-in zlib replacement in
- many apps: The z_stream struct, optional memory allocation
- callbacks
- deflateInit/deflateInit2/deflate/deflateReset/deflateEnd/deflateBound
- inflateInit/inflateInit2/inflate/inflateReset/inflateEnd
- compress, compress2, compressBound, uncompress
- CRC-32, Adler-32 - Using modern, minimal code size, CPU cache
- friendly routines. Supports raw deflate streams or standard zlib
- streams with adler-32 checking.
-
- Limitations:
- The callback API's are not implemented yet. No support for gzip
- headers or zlib static dictionaries. I've tried to closely emulate
- zlib's various flavors of stream flushing and return status codes,
- but there are no guarantees that miniz.c pulls this off perfectly.
-
- * PNG writing: See the tdefl_write_image_to_png_file_in_memory()
- function, originally written by Alex Evans. Supports 1-4
- bytes/pixel images.
-
- * ZIP archive API notes:
-
- The ZIP archive API's where designed with simplicity and
- efficiency in mind, with just enough abstraction to get the job
- done with minimal fuss. There are simple API's to retrieve file
- information, read files from existing archives, create new
- archives, append new files to existing archives, or clone archive
- data from one archive to another. It supports archives located in
- memory or the heap, on disk (using stdio.h), or you can specify
- custom file read/write callbacks.
-
- - Archive reading: Just call this function to read a single file
- from a disk archive:
-
- void *mz_zip_extract_archive_file_to_heap(const char
- *pZip_filename, const char *pArchive_name, size_t *pSize, mz_uint
- zip_flags);
-
- For more complex cases, use the "mz_zip_reader" functions. Upon
- opening an archive, the entire central directory is located and
- read as-is into memory, and subsequent file access only occurs when
- reading individual files.
-
- - Archives file scanning: The simple way is to use this function
- to scan a loaded archive for a specific file:
-
- int mz_zip_reader_locate_file(mz_zip_archive *pZip, const char
- *pName, const char *pComment, mz_uint flags);
-
- The locate operation can optionally check file comments too,
- which (as one example) can be used to identify multiple versions of
- the same file in an archive. This function uses a simple linear
- search through the central directory, so it's not very fast.
-
- Alternately, you can iterate through all the files in an archive
- (using mz_zip_reader_get_num_files()) and retrieve detailed info on
- each file by calling mz_zip_reader_file_stat().
-
- - Archive creation: Use the "mz_zip_writer" functions. The ZIP
- writer immediately writes compressed file data to disk and builds
- an exact image of the central directory in memory. The central
- directory image is written all at once at the end of the archive
- file when the archive is finalized.
-
- The archive writer can optionally align each file's local header
- and file data to any power of 2 alignment, which can be useful when
- the archive will be read from optical media. Also, the writer
- supports placing arbitrary data blobs at the very beginning of ZIP
- archives. Archives written using either feature are still readable
- by any ZIP tool.
-
- - Archive appending: The simple way to add a single file to an
- archive is to call this function:
-
- mz_bool mz_zip_add_mem_to_archive_file_in_place(const char
- *pZip_filename, const char *pArchive_name, const void *pBuf, size_t
- buf_size, const void *pComment, mz_uint16 comment_size, mz_uint
- level_and_flags);
-
- The archive will be created if it doesn't already exist,
- otherwise it'll be appended to. Note the appending is done in-place
- and is not an atomic operation, so if something goes wrong during
- the operation it's possible the archive could be left without a
- central directory (although the local file headers and file data
- will be fine, so the archive will be recoverable).
-
- For more complex archive modification scenarios:
- 1. The safest way is to use a mz_zip_reader to read the existing
- archive, cloning only those bits you want to preserve into a new
- archive using using the mz_zip_writer_add_from_zip_reader()
- function (which compiles the compressed file data as-is). When
- you're done, delete the old archive and rename the newly written
- archive, and you're done. This is safe but requires a bunch of
- temporary disk space or heap memory.
-
- 2. Or, you can convert an mz_zip_reader in-place to an
- mz_zip_writer using mz_zip_writer_init_from_reader(), append new
- files as needed, then finalize the archive which will write an
- updated central directory to the original archive. (This is
- basically what mz_zip_add_mem_to_archive_file_in_place() does.)
- There's a possibility that the archive's central directory could be
- lost with this method if anything goes wrong, though.
-
- - ZIP archive support limitations:
- No spanning support. Extraction functions can only handle
- unencrypted, stored or deflated files. Requires streams capable of
- seeking.
-
- * This is a header file library, like stb_image.c. To get only a
- header file, either cut and paste the below header, or create
- miniz.h, #define MINIZ_HEADER_FILE_ONLY, and then include miniz.c
- from it.
-
- * 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
-
- * On platforms using glibc, Be sure to "#define _LARGEFILE64_SOURCE
- 1" before including miniz.c to ensure miniz uses the 64-bit
- variants: fopen64(), stat64(), etc. Otherwise you won't be able to
- process large files (i.e. 32-bit stat() fails for me on files >
- 0x7FFFFFFF bytes).
