Redirection, Xterms, and Flushing STDIN

[James Cameron]

First of all, thanks to all you responded to my xterm question regarding
redirection.  The solution is:

$ xterm -e sh -c 'A SHELL COMMAND'

ie, the solution for me was:

$ xterm -title DEMO -name DEMO -e sh -c 'demo1 input/sentences_1 < input/numbers_1'

(Sorry for the length of that...I too hate seeing long lines in
 articles)


Ok, I have come across another problem now.  It seems something funny
is happening with my C program concerning the redirection.  What I
want to happen is that after my output finishes, I want it to ask
the user to hit enter to continue.  The reason for this is that I am
executing it in an xterm and if I don't have some kind of wait command
the xterm will finish upon completetion of said program.  

For some reason, fflush(stdin) doesn't clear it for me when I 
use this redirection.  

The ugly solution is to add a shell prompting script to the end of
that xterm execution string such as

'demo1 input/sentences_1 < input/numbers_1;demowait'

but that seems to be an unnecessary workaround.

The code in the C program to wait is simply this:

  printf("\n\nHit <enter> to close window: ");
  fflush(stdin);
  fflush(fp);
  ch = getchar();

If anyone has any ideas, I would greatly appreciate it.
