ZSTD_decodeLiteralsBlock()

size_t ZSTD_decodeLiteralsBlock ( ZSTD_DCtx * dctx, const void * src, size_t srcSize, void * dst, size_t dstCapacity, const streaming_operation streaming )

extern

ZSTD_decodeLiteralsBlock() : Where it is possible to do so without being stomped by the output during decompression, the literals block will be stored in the dstBuffer. If there is room to do so, it will be stored in full in the excess dst space after where the current block will be output. Otherwise it will be stored at the end of the current dst blockspace, with a small portion being stored in dctx->litExtraBuffer to help keep it "ahead" of the current output write.

Returns

: nb of bytes read from src (< srcSize ) note : symbol not declared but exposed for fullbench
