-/* miniz.c 3.0.0 - public domain deflate/inflate, zlib-subset, ZIP reading/writing/appending, PNG writing
- See "unlicense" statement at the end of this file.
- Rich Geldreich , 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).
