21 Opens two files and performs a comparison of the binary values of
|
|
|
22 the corresponding data bytes of the files. If any differences are
|
|
|
23 encountered, the file offset (address) and the values of the bytes
|
|
|
24 from each file are displayed in hexadecimal.

26 <para>
|
|
|
27 The comparison ends when end-of-file is encountered on either
|
|
|
28 file. A summary of the number of bytes compared and the number of
|
|
|
29 differences found is then displayed.
