Get the CRC32 for the given (word,byte) combo. This is a computation defined by PKzip.
- Parameters
-
| W | The word to start with. |
| B | The byte to combine it with. |
- Returns
- The CRC-ized result.
| Int32 UniExtensions.Zlib.CRC32.GetCrc32 |

System.IO.Stream |
input | ) |
|
|
inline |
Returns the CRC32 for the specified stream.
- Parameters
-
| input | The stream over which to calculate the CRC32 |
- Returns
- the CRC32 calculation

inline |
Returns the CRC32 for the specified stream, and writes the input into the output stream.
- Parameters
-
| input | The stream over which to calculate the CRC32 |
| output | The stream into which to deflate the input |
- Returns

Update the value for the running CRC32 using the given block of bytes. This is useful when using the CRC32() class in a Stream.
- Parameters
-
| block | block of bytes to slurp |
| offset | starting point in the block |
| count | how many bytes within the block to slurp |
| Int32 UniExtensions.Zlib.CRC32.Crc32Result |
|
get |
Indicates the current CRC for all blocks slurped in.
| Int64 UniExtensions.Zlib.CRC32.TotalBytesRead |
|
get |
indicates the total number of bytes read on the CRC stream. This is used when writing the ZipDirEntry when compressing files.
