Thanks! Got it working now. If I do:
stdin_fd = sys.stdin.fileno() during import time and then use that with os.read (either directly or indirectly through streams), will it also be translated correctly for the other non-C backends? > There are two official ways: > > 1. use directly os.read/os.open/os.write, rather tedious if you ask me > 2. use interfaces that are present in pypy/rlib/streamio.py.
