I have a process I'm starting and putting into a pipe:

set pipe [open "| \"$executable_name\" \"$file\""]

after this process starts, I want to feed the executable that I'm calling
more parameters. If I use exec, another instance of the executable is
started, which is not what I want. Instead, I want to just call the same
executable and have it open the new file.

I believe that this is possible with this executable becuase in WinXP, I can
open two files separately and the both go into only one instance of the same
program.

So, I feed it a fileevent, which does nothing but open another instance:

fileevent $pipe readable $file

Is this the right construction? Thank you in advance for your help.
