HEXDUMP - Hexadecimal file dump, in C

HEXDUMP is a simple program to print the contents of a file, byte by byte, in hexadecimal format. This sort of information can be useful when determining the format of a file, checking for byte-swapping, or other common tasks.

Sample output of the program looks like this:

        HEXDUMP: Hexadecimal dump of file: box.3ds.
