st char* src, char* dst, int srcSize, int dstCapacity, int acceleration);
</b><p>  A variant of LZ4_compress_fast_extState().

  Using this variant avoids an expensive initialization step. It is only safe
  to call if the state buffer is known to be correctly initialized already
  (see above comment on LZ4_resetStream_fast() for a definition of "correctly
  initialized"). From a high level, the difference is that this function
  initializes the provided state with a call to something like
  LZ4_resetStream_
