What's the preferred method of determining within a C program whether a user
has redirected stdout or stdin on the command line?  Interrogating an 'fstat'
structure's file mode works on my PC, but there must be a more elegant,
portable way of doing this, right?

Also, how can one redirect stderr to a file from a (DOS) command line?

Any help from you wizards would be greatly appreciated!
