Petr Viktorin <[email protected]> added the comment:
To follow up on the StackOverflow discussion: A call to PyErr_Print should
invoke sys.excepthook. Unless sys.excepthook was changed, this should print the
message *and* flush standard output.
If it doesn't, I recommend investigating why.
If that does not work, you can flush stderr with two function calls:
sys_stderr = PySys_GetObject("stderr");
PyObject_CallMethodNoArgs(sys_stderr, "flush");
plus the necessary error handling if any returns NULL, of course.
And/or the same thing with stdout. The flush_io function does exactly this (for
both stdout and stderr).
I don't think this is general enough to expose as an API -- IMO it's better to
be explicit and call the flush method as above.
