JavaScriptView Source Request Example

Gemstone.IO.Checksums.ChecksumExtensions.ChecksumExtensions.CrcCCITTChecksum = function(data, startIndex, length);

Parameters

data Byte: Data buffer to perform check-sum on.
startIndex Int32: Starts index in data buffer to begin check-sum.
length Int32: Total number of bytes from startIndex to perform check-sum over.

Return Value

UInt16
Computed CRC-CCITT checksum over the specified portion of the buffer.

Usage Note

In Visual Basic and C#, you can call this method as an instance method on any object of type Byte. When you use instance method syntax to call this method, omit the first parameter. For more information, see Extension Methods (Visual Basic) or Extension Methods (C# Programming Guide).

Remarks

The CRC-CCITT is a table based 16-bit CRC popular for modem protocols defined for use by the Consultative Committee on International Telegraphy and Telephony (CCITT)
