crc32c computes the CRC32 (Castagnoli) check value of an input data.


W byte number of input data, the value of W includes 1, 2, 4, 8, 16, 32, 64.
crcInitStrm initialize crc32 value
inStrm input messages to be checked
inPackLenStrm effetive lengths of input message pack, 1~W. 0 means end of message
endInPackLenStrm end flag of inPackLenStrm, 1 “false” for 1 message, 1 “true” means no message anymore.
outStrm crc32 result to output
endOutStrm end flag of outStrm
