[Swig-user] How to receive a FILE* from Python under MinGW?

[John P. <joh...@st...>]

Hi all

There is fairly well-known problem on MinGW with passing FILE pointers
to Python. The problem seems to be that Python depends on a different
version of msvcrt*.dll to that which MinGW depends on, and these
different C runtimes provide different FILE implementations.

The upshot of that seems to be that file objects created in Python via
the 'file(...)' command can't safely be used in a SWIG module. It can be
done perfectly (using SWIG typemap and PyFile_AsFile) on Linux but it
fails with a segfault on Windows.

What is the best possible workaround for this? Surely someone must have
found a satisfactory solution to this problem?
