CCRC16

CCRC16 class does not have a base class.

CCRC16 class assists you in generating CRC16 checksums.

CRC16 checksums can be generated in two modes: accumulative and non-accumulative.

The accumulative mode is applied when the data for which the checksum is calculated (data) represents one or more continuous memory block(s) or when the data is created at runtime in many steps (for instance, when reading a file).

Non-accumulative mode can be applied when the data represents only one continuous memory block.

Note. When the data represents just one continuous memory block, both methods can be applied.

To generate the checksum in the accumulative mode, perform the following:

• Instantiate a CCRC16 object.

• Call the Update member function for each continuous memory block of data to perform the calculations.

• Call the Final or call the FinalHex member function to obtain the checksum.

  Note. Call the FinalHex member function when you need to retrieve the hexadecimal string representation of the checksum.

To generate the checksum in the non-accumulative mode, perform the following:

• Call the Calculate or the CalculateHex static member function to calculate and retrieve the checksum.

  Note. Call the CalculateHex static member function when you need to retrieve the hexadecimal string representation of the checksum.
