+* Streaming decompression
+*
+* A ZBUFFv05_DCtx object is required to track streaming operations.
+* Use ZBUFFv05_createDCtx() and ZBUFFv05_freeDCtx() to create/release resources.
+* Use ZBUFFv05_decompressInit() to start a new decompression operation,
+* or ZBUFFv05_decompressInitDictionary() if decompression requires a dictionary.
+* Note that ZBUFFv05_DCtx objects can be reused multiple times.
+*
+* Use ZBUFFv05_decompressContinue() repetitively to consume your input.
+* *srcSizePtr and *dstCapacityPtr can be any size.
+* The function will report how many bytes were read or written by modifying *srcSizePtr and *dstCapacityPtr.
+* Note that it may not consume the entire input, in which case it's up to the caller to present remaining input again.
+* The content of @dst will be overwritten (up to *dstCapacityPtr) at each function 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 only a hint, to help latency)
+* or 0 when a frame is completely decoded
+* or an error code, which can be tested using ZBUFFv05_isError().
+*
+* Hint : recommended buffer sizes (not compulsory) : ZBUFFv05_recommendedDInSize() / ZBUFFv05_recommendedDOutSize()
+* output : ZBUFFv05_recommendedDOutSize==128 KB block size is the internal unit, it ensures it's always possible to write a full block when decoded.
+* input : ZBUFFv05_recommendedDInSize==128Kb+3; just follow indications from ZBUFFv05_decompressContinue() to minimize latency. It should always be <= 128 KB + 3 .
