Redirecting I/O in embedded Python

[Bertram Scharpf]

Hi,

in one of my C programs, I call embedded Python code. Now, I
would like to redirect stdin/stdout to strings I can assign
to/read out within the C code.

This should be a solvable problem creating modules that have
a member function 'write' or 'readline' respectively and
assigning them to sys.stdin and sys.stdout.

Before I do this work, I would like to ask if there is a
reported standard way to do it or if there is even the
finished code to be obtained anywhere on the web.

Thanks in advance,

Bertram

Put the library reference under your pillow tonight, and read the
sections on stringio and cstringio in the morning.

Hi Heather,

Put the library reference under your pillow tonight, and read the
sections on stringio and cstringio in the morning.

Yes, I did already think of that solution. But compared to
that mentioned above, it wouldn't be less effort in
programming for me, but rather a loss in efficiency I
suppose. (Additional modules would be loaded and strings
would be copied once more.)

Thank you, anyway.
