I am piping two programs together. In testing this on Win32, I found it
useful to start by working with redirection using the shell redirection
syntax '$ executable-name <filedata-ondisk' but in my shell scripts or
in the console this would hardly ever make sense to do. So the answer
is "piping". In the shell. Therefore i don't think that freopen() can
help me because i do not have control over what the "feeding-from"
application is doing (in source code); only over what the "feed-ee"
application does when invoked in this context (on the right hand side
of a pipe, in the shell).

   Thanks!
