|
|
* \brief The public API of liblzma data compression library
|
|
*
|
|
* liblzma is a public domain general-purpose data compression library with
|
|
* a zlib-like API. The native file format is .xz, but also the old .lzma
|
|
* format and raw (no headers) streams are supported. Multiple compression
|
|
* algorithms (filters) are supported. Currently LZMA2 is the primary filter.
|
|
*
|
|
* liblzma is part of XZ Utils <http://tukaani.org/xz/>. XZ Utils includes
|
|
* a gzip-like command line tool named xz and some other tools. XZ Utils
|
|
* is developed and maintained by Lasse Collin.
|
|
*
|
|
* Major parts of liblzma are based on Igor Pavlov's public domain LZMA SDK
|
|
* <http://7-zip.org/sdk.html>.
|
|
*
|
|
* The SHA-256 implementation is based on the public domain code found from
|
|
* 7-Zip <http://7-zip.org/>, which has a modified version of the public
|
|
* domain SHA-256 code found from Crypto++ <http://www.cryptopp.com/>.
|
|
* The SHA-256 code in Crypto++ was written by Kevin Springle and Wei Dai.

/*****************************
|
|
* Required standard headers *
|
|
*****************************/
|
|
|
|
/*
|
|
* liblzma API headers need some standard types and macros. To allow
|
|
* including lzma.h without requiring the application to include other
|
|
* headers first, lzma.h includes the required standard headers unless
|
|
* they already seem to be included already or if LZMA_MANUAL_HEADERS
|
|
* has been defined.
|
|
*
|
|
* Here's what types and macros are needed and from which headers:
|
|
* - stddef.h: size_t, NULL
|
|
* - stdint.h: uint8_t, uint32_t, uint64_t, UINT32_C(n), uint64_C(n),
|
|
* UINT32_MAX, UINT64_MAX
|
|
*
|
|
* However, inttypes.h is a little more portable than stdint.h, although
|
|
* inttypes.h declares some unneeded things compared to plain stdint.h.
|
|
*
|
|
* The hacks below aren't perfect, specifically they assume that inttypes.h
|
|
* exists and that it typedefs at least uint8_t, uint32_t, and uint64_t,
|
|
* and that, in case of incomplete inttypes.h, unsigned int is 32-bit.
|
|
* If the application already takes care of setting up all the types and
|
|
* macros properly (for example by using gnulib's stdint.h or inttypes.h),
|
|
* we try to detect that the macros are already defined and don't include
|
|
* inttypes.h here again. However, you may define LZMA_MANUAL_HEADERS to
|
|
* force this file to never include any system headers.
|
|
*
|
|
* Some could argue that liblzma API should provide all the required types,
|
|
* for example lzma_uint64, LZMA_UINT64_C(n), and LZMA_UINT64_MAX. This was
|
|
* seen as an unnecessary mess, since most systems already provide all the
|
|
* necessary types and macros in the standard headers.
|
|
*
|
|
* Note that liblzma API still has lzma_bool, because using stdbool.h would
|
|
* break C89 and C++ programs on many systems. sizeof(bool) in C99 isn't
|
|
* necessarily the same as sizeof(bool) in C++.
