Introduction
LZ4 is lossless compression algorithm, providing compression speed at 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.
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.
An additional format, called LZ4 frame specification (doc/lz4_Frame_format.md),
take care of encoding standard metadata alongside LZ4-compressed blocks.
Frame format is required for interoperability.
It is delivered through a companion API, declared in lz4frame.h.

In:
RangeCoder is normalized
if (p->dicPos == limit)
{
LzmaDec_TryDummy() was called before to exclude LITERAL and MATCH-REP cases.
So first symbol can be only MATCH-NON-REP. And if that MATCH-NON-REP symbol
is not END_OF_PAYALOAD_MARKER, then function returns error code.
}
Processing:
first LZMA symbol will be decoded in any case
All checks for limits are at the end of main loop,
It will decode new LZMA-symbols while (p->buf < bufLimit && dicPos < limit),
RangeCoder is still without last normalization when (p->buf < bufLimit) is being checked.
Out:
RangeCoder is normalized
Result:
SZ_OK - OK
SZ_ERROR_DATA - Error
