Did you read my first request for this topic?

I am thinking about the following application.
A limited execution environment will be created that forbids to
directly use standard file channels. For example, I must avoid that
output is written to STDOUT by calls to the TCL function "puts" before
the own data processing is finished. But these calls need a place to
store the output.
- How can the data be stored or redirected to a temporary file?
  or
- All file system calls will be intercepted to store the data into a
buffer that can be copied to a variable later.
