-*  Streaming compression - howto
-*
-*  A ZBUFF_CCtx object is required to track streaming operation.
-*  Use ZBUFF_createCCtx() and ZBUFF_freeCCtx() to create/release resources.
-*  ZBUFF_CCtx objects can be reused multiple times.
-*
-*  Start by initializing ZBUF_CCtx.
-*  Use ZBUFF_compressInit() to start a new compression operation.
-*  Use ZBUFF_compressInitDictionary() for a compression which requires a dictionary.
-*
-*  Use ZBUFF_compressContinue() repetitively to consume input stream.
-*  *srcSizePtr and *dstCapacityPtr can be any size.
-*  The function will report how many bytes were read or written within *srcSizePtr and *dstCapacityPtr.
-*  Note that it may not consume the entire input, in which case it's up to the caller to present again remaining data.
-*  The content of `dst` will be overwritten (up to *dstCapacityPtr) at each call, so save its content if it matters or change @dst .
-*  @return : a hint to preferred nb of bytes to use as input for next function call (it's just a hint, to improve latency)
-*            or an error code, which can be tested using ZBUFF_isError().
-*
-*  At any moment, it's possible to flush whatever data remains within buffer, using ZBUFF_compressFlush().
-*  The nb of bytes written into `dst` will be reported into *dstCapacityPtr.
-*  Note that the function cannot output more than *dstCapacityPtr,
-*  therefore, some content might still be left into internal buffer if *dstCapacityPtr is too small.
-*  @return : nb of bytes still present into internal buffer (0 if it's empty)
-*            or an error code, which can be tested using ZBUFF_isError().
-*
-*  ZBUFF_compressEnd() instructs to finish a frame.
-*  It will perform a flush and write frame epilogue.
-*  The epilogue is required for decoders to consider a frame completed.
-*  Similar to ZBUFF_compressFlush(), it may not be able to output the entire internal buffer content if *dstCapacityPtr is too small.
-*  In which case, call again ZBUFF_compressFlush() to complete the flush.
-*  @return : nb of bytes still present into internal buffer (0 if it's empty)
-*            or an error code, which can be tested using ZBUFF_isError().
-*
-*  Hint : recommended buffer sizes (not compulsory) : ZBUFF_recommendedCInSize / ZBUFF_recommendedCOutSize
-*  input : ZBUFF_recommendedCInSize==128 KB block size is the internal unit, it improves latency to use this value (skipped buffering).
-*  output : ZBUFF_recommendedCOutSize==ZSTD_compressBound(128 KB) + 3 + 3 : ensures it's always possible to write/flush/end a full block. Skip some buffering.
-*  By using both, it ensures that input will be entirely consumed, and output will always contain the result, reducing intermediate buffering.
