There shouldn't be any problem with files opened read-only.

Hello pythoners,
When I create temporary file using the tempfile module, and forkI)
later on in my program, I always see errors when the program exits. Is
this because the child process deletes temp file?
Here's a stripped down version of my script that exhibits this
problem:
#!/usr/bin/p

I understand the security issues of temporary file (as explained in
Python doc) but maybe standard lib need a NamedTemporaryFile that
could be used by another process.

Hi,
I want to create a temporary file, read it in an external command and
finally delete it (in Windows XP).
I try to use tempfile module but it doesn't work, the file couldn't be
open by my other process (error like: SP2-0310: unable to open file "c:

Ok, thanks for the advice.

Hi all
I need to generate potentially large reports from a database, and I
want to offer the option of print preview before actually printing
(using wxPython). I figure that the best way to achieve this is to
write the report to a temporary file, or more likely to a temporary
directory with a
