Hello,
THE PROBLEM:
I am having a problem that I have seen asked quite a bit on the web, with
little to no follow up.
The problem is essentially this. When embedding (LoadLibraryA()) the python
interpreter dll
in a non-windows application the developer must first create a console for
python to do output/input with.
I properly initialize the CRT and AllocConsole() to do this. I then
GetSTDHandle() for stdin and stdout accordingly
and open those handles with the requisite flags "read" for STDIN and "write"
for stdout. This all works great
and is then verified and tested to work by printf() and fgets(). This issue
however happens when attempting
to PyRun_InteractiveLoop() and PyRun_SimpleString(). A
PyRun_SimpleString("print 'test'") displays nothing in my
freshly allocated console window. Similarly a PyRun_InteractiveLoop(stdin,
NULL); yields nothing either even though
the line printf("testing"); directly ahead of it works just fine. Does
anyone have insight on how I can make this work
with the freshly allocated console's stdin/stdout/stderr?
SPECULATION:
That is the question, so now on to the speculation. I suspect that something
in the python runtime doesn't "get handles"
correctly for STDIN and STDOUT upon initialization. I have perused the
source code to find out exactly how this is done
and I suspect that it starts in PyInitializeEx with calls to
PySys_GetObject("stdin") and "stdout" accordingly. However I
don't actually see where this translates into the Python runtime checking
with the C-runtime for the "real" handles to STDIN and STDOUT. I dont ever
see the Python runtime "ask the system" where his handles to STDIN and
STDOUT are.
SUBSEQUENT QUESTION:
Is there anything I can do to initialize the Python interpreter (running as
a dll) pointing him at his appropriate STDIN and STDOUT
handles?
