Hello again,
I wanted to give your solution a try, but got stuck.
The file that I want to replace the "standard input" with is a pseudo file
object with a custom read method. I have a hard time finding out how
to have a file descriptor (or fileno) associated with it.
I tried inheriting from the "file" class (using a dummy file on disk), and
then
overriding the read() and __init__() method. To test I used
os.read(my_file_no,1),
but it reads the contents of my dummy file rather than using my read method.
So obviously it does some low level stuff there...
Again I have the feeling this is impossible, but I thought that the last
time too :)
