Introduction
LZ4 is lossless compression algorithm, providing compression speed at 400 MB/s per core,
LZ4 is lossless compression algorithm, providing compression speed >500 MB/s per core,
scalable with multi-cores CPU. It features an extremely fast decoder, with speed in
multiple GB/s per core, typically reaching RAM speed limits on multi-core systems.
The LZ4 compression library provides in-memory compression and decompression functions.
It gives full buffer control to user.
Compression can be done in:
- a single step (described as Simple Functions)
- a single step, reusing a context (described in Advanced Functions)
- unbounded multiple steps (described as Streaming compression)
lz4.h provides block compression functions. It gives full buffer control to user.
Decompressing an lz4-compressed block also requires metadata (such as compressed size).
Each application is free to encode such metadata in whichever way it wants.
lz4.h generates and decodes LZ4-compressed blocks (doc/lz4_Block_format.md).
Decompressing such a compressed block requires additional metadata.
Exact metadata depends on exact decompression function.
For the typical case of LZ4_decompress_safe(),
metadata includes block's compressed size, and maximum bound of decompressed size.
Each application is free to encode and pass such metadata in whichever way it wants.
An additional format, called LZ4 frame specification (doc/lz4_Frame_format.md),
take care of encoding standard metadata alongside LZ4-compressed blocks.
If your application requires interoperability, it's recommended to use it.
A library is provided to take care of it, see lz4frame.h.
lz4.h only handle blocks, it can not generate Frames.
Blocks are different from Frames (doc/lz4_Frame_format.md).
Frames bundle both blocks and metadata in a specified manner.
Embedding metadata is required for compressed data to be self-contained and portable.
Frame format is delivered through a companion API, declared in lz4frame.h.
The `lz4` CLI can only manage frames.

/*! In-place compression and decompression
*
* It's possible to have input and output sharing the same buffer,
* for highly contrained memory environments.
* In both cases, it requires input to lay at the end of the buffer,
* and decompression to start at beginning of the buffer.
* Buffer size must feature some margin, hence be larger than final size.
*
* |<------------------------buffer--------------------------------->|
* |<-----------compressed data--------->|
* |<-----------decompressed size------------------>|
* |<----margin---->|
*
* This technique is more useful for decompression,
* since decompressed size is typically larger,
* and margin is short.
*
* In-place decompression will work inside any buffer
* which size is >= LZ4_DECOMPRESS_INPLACE_BUFFER_SIZE(decompressedSize).
* This presumes that decompressedSize > compressedSize.
* Otherwise, it means compression actually expanded data,
* and it would be more efficient to store such data with a flag indicating it's not compressed.
* This can happen when data is not compressible (already compressed, or encrypted).
*
* For in-place compression, margin is larger, as it must be able to cope with both
* history preservation, requiring input data to remain unmodified up to LZ4_DISTANCE_MAX,
* and data expansion, which can happen when input is not compressible.
* As a consequence, buffer size requirements are much higher,
* and memory savings offered by in-place compression are more limited.
*
* There are ways to limit this cost for compression :
* - Reduce history size, by modifying LZ4_DISTANCE_MAX.
* Note that it is a compile-time constant, so all compressions will apply this limit.
* Lower values will reduce compression ratio, except when input_size < LZ4_DISTANCE_MAX,
* so it's a reasonable trick when inputs are known to be small.
* - Require the compressor to deliver a "maximum compressed size".
* This is the `dstCapacity` parameter in `LZ4_compress*()`.
* When this size is < LZ4_COMPRESSBOUND(inputSize), then compression can fail,
* in which case, the return code will be 0 (zero).
* The caller must be ready for these cases to happen,
* and typically design a backup scheme to send data uncompressed.
* The combination of both techniques can significantly reduce
* the amount of margin required for in-place compression.
*
* In-place compression can work in any buffer
* which size is >= (maxCompressedSize)
* with maxCompressedSize == LZ4_COMPRESSBOUND(srcSize) for guaranteed compression success.
* LZ4_COMPRESS_INPLACE_BUFFER_SIZE() depends on both maxCompressedSize and LZ4_DISTANCE_MAX,
* so it's possible to reduce memory requirements by playing with them.

* TIFFWriteDirectory() is first called, and will be reset when
* changing directory.
*
* The typical sequence of calls is:
* TIFFOpen()
* [ TIFFCreateDirectory(tif) ]
* Set fields with calls to TIFFSetField(tif, ...)
* TIFFDeferStrileArrayWriting(tif)
* TIFFWriteCheck(tif, ...)

ISO C++ uses a 'std::streamsize' type to define counts. This makes
it similar to, (but perhaps not the same as) size_t.
The std::ios::pos_type is used to represent stream positions as used
by tellg(), tellp(), seekg(), and seekp(). This makes it similar to
(but perhaps not the same as) 'off_t'. The std::ios::streampos type
is used for character streams, but is documented to not be an
integral type anymore, so it should *not* be assigned to an integral
type.
The std::ios::off_type is used to specify relative offsets needed by
the variants of seekg() and seekp() which accept a relative offset
argument.
Useful prototype knowledge:
Obtain read position
ios::pos_type basic_istream::tellg()
Set read position
basic_istream& basic_istream::seekg(ios::pos_type)
basic_istream& basic_istream::seekg(ios::off_type, ios_base::seekdir)
Read data
basic_istream& istream::read(char *str, streamsize count)
Number of characters read in last unformatted read
streamsize istream::gcount();
Obtain write position
ios::pos_type basic_ostream::tellp()
Set write position
basic_ostream& basic_ostream::seekp(ios::pos_type)
basic_ostream& basic_ostream::seekp(ios::off_type, ios_base::seekdir)
Write data
