-
-  A ZSTD_DCtx object is required to track streaming operations.
-  Use ZSTD_createDCtx() / ZSTD_freeDCtx() to manage it.
-  A ZSTD_DCtx object can be re-used multiple times.
-
-  First optional operation is to retrieve frame parameters, using ZSTD_getFrameParams(), which doesn't consume the input.
-  It can provide the minimum size of rolling buffer required to properly decompress data,
-  and optionally the final size of uncompressed content.
-  (Note : content size is an optional info that may not be present. 0 means : content size unknown)
-  Frame parameters are extracted from the beginning of compressed frame.
-  The amount of data to read is variable, from ZSTD_frameHeaderSize_min to ZSTD_frameHeaderSize_max (so if `srcSize` >= ZSTD_frameHeaderSize_max, it will always work)
-  If `srcSize` is too small for operation to succeed, function will return the minimum size it requires to produce a result.
-  Result : 0 when successful, it means the ZSTD_frameParams structure has been filled.
-          >0 : means there is not enough data into `src`. Provides the expected size to successfully decode header.
-           errorCode, which can be tested using ZSTD_isError()
-
-  Start decompression, with ZSTD_decompressBegin() or ZSTD_decompressBegin_usingDict().
-  Alternatively, you can copy a prepared context, using ZSTD_copyDCtx().
-
-  Then use ZSTD_nextSrcSizeToDecompress() and ZSTD_decompressContinue() alternatively.
-  ZSTD_nextSrcSizeToDecompress() tells how much bytes to provide as 'srcSize' to ZSTD_decompressContinue().
-  ZSTD_decompressContinue() requires this exact amount of bytes, or it will fail.
-  ZSTD_decompressContinue() needs previous data blocks during decompression, up to (1 << windowlog).
-  They should preferably be located contiguously, prior to current block. Alternatively, a round buffer is also possible.
-
-  @result of ZSTD_decompressContinue() is the number of bytes regenerated within 'dst' (necessarily <= dstCapacity)
-  It can be zero, which is not an error; it just means ZSTD_decompressContinue() has decoded some header.
-
-  A frame is fully decoded when ZSTD_nextSrcSizeToDecompress() returns zero.
-  Context can then be reset to start a new decompression.

+  Streaming decompression, direct mode (bufferless) 
+ 
+  A ZSTD_DCtx object is required to track streaming operations. 
+  Use ZSTD_createDCtx() / ZSTD_freeDCtx() to manage it. 
+  A ZSTD_DCtx object can be re-used multiple times. 
+ 
+  First optional operation is to retrieve frame parameters, using ZSTD_getFrameParams(), which doesn't consume the input. 
+  It can provide the minimum size of rolling buffer required to properly decompress data, 
+  and optionally the final size of uncompressed content. 
+  (Note : content size is an optional info that may not be present. 0 means : content size unknown) 
+  Frame parameters are extracted from the beginning of compressed frame. 
+  The amount of data to read is variable, from ZSTD_frameHeaderSize_min to ZSTD_frameHeaderSize_max (so if `srcSize` >= ZSTD_frameHeaderSize_max, it will always work) 
+  If `srcSize` is too small for operation to succeed, function will return the minimum size it requires to produce a result. 
+  Result : 0 when successful, it means the ZSTD_frameParams structure has been filled. 
+          >0 : means there is not enough data into `src`. Provides the expected size to successfully decode header. 
+           errorCode, which can be tested using ZSTD_isError() 
+ 
+  Start decompression, with ZSTD_decompressBegin() or ZSTD_decompressBegin_usingDict(). 
+  Alternatively, you can copy a prepared context, using ZSTD_copyDCtx(). 
+ 
+  Then use ZSTD_nextSrcSizeToDecompress() and ZSTD_decompressContinue() alternatively. 
+  ZSTD_nextSrcSizeToDecompress() tells how much bytes to provide as 'srcSize' to ZSTD_decompressContinue(). 
+  ZSTD_decompressContinue() requires this exact amount of bytes, or it will fail. 
+  ZSTD_decompressContinue() needs previous data blocks during decompression, up to (1 << windowlog). 
+  They should preferably be located contiguously, prior to current block. Alternatively, a round buffer is also possible. 
+ 
+  @result of ZSTD_decompressContinue() is the number of bytes regenerated within 'dst' (necessarily <= dstCapacity) 
+  It can be zero, which is not an error; it just means ZSTD_decompressContinue() has decoded some header. 
+ 
+  A frame is fully decoded when ZSTD_nextSrcSizeToDecompress() returns zero. 
+  Context can then be reset to start a new decompression.

+      + variants _usingDict() are also allowed 
+      + copyCCtx() and copyDCtx() work too 
+    - When a block is considered not compressible enough, ZSTD_compressBlock() result will be zero. 
+      In which case, nothing is produced into `dst`. 
+      + User must test for such outcome and deal directly with uncompressed data
