|

*
|
|
* The "Fletcher Checksum" was proposed in a paper by John G. Fletcher of
|
|
* Lawrence Livermore Labs. The Fletcher Checksum was proposed as an
|
|
* alternative to cyclical redundancy checks because it provides error-
|
|
* detection properties similar to cyclical redundancy checks but at the
|
|
* cost of a simple summation technique. Its characteristics were first
|
|
* published in IEEE Transactions on Communications in January 1982. One
|
|
* version has been adopted by ISO for use in the class-4 transport layer
|
|
* of the network protocol.
|
|
*
|
|
* This program expects:
|
|
* stdin: The input file to compute a checksum for. The input file
|
|
* not be longer than 256 bytes.
|
|
* stdout: Copied from the input file with the Fletcher's Checksum
|
|
* inserted 8 bytes after the beginning of the file.
|
|
* stderr: Used to print out error messages.
