- LZ4_decompress_fast_continue

_continue() :
These decoding functions allow decompression of multiple blocks in "streaming" mode.
Previously decoded blocks must still be available at the memory position where they were decoded.
If it's not possible, save the relevant part of decoded data into a safe buffer,
and indicate where it stands using LZ4_setStreamDecode()
- LZ4_decompress_fast_usingDict
int LZ4_decompress_fast_usingDict(const(char)* source, char* dest, int originalSize, const(char)* dictStart, int dictSize)
Advanced decoding functions :
_usingDict() :
These decoding functions work the same as "_continue" ones,
the dictionary must be explicitly provided within parameters
- LZ4_decompress_generic
int LZ4_decompress_generic(const(char)* source, char* dest, int inputSize, int outputSize, int endOnInput, int partialDecoding, int targetOutputSize, int dict, const(ubyte)* lowPrefix, const(ubyte)* dictStart, size_t dictSize)
This generic decompression function cover all use cases.
It shall be instantiated several times, using different sets of directives
Note that it is essential this generic function is really inlined,
in order to remove useless branches during compilation optimization.

LZ4_initStream
Use this function once, to init a newly allocated LZ4_stream_t structure
Return : 1 if OK, 0 if error

Loading a size of 0 is allowed (same effect as no dictionary).
Return : 1 if OK, 0 if error
