Hi Liam,


os.pipe() comes from the block of code near the top of os.py:

http://cvs.sourceforge.net/viewcvs.py/python/python/dist/src/Lib/os.py?rev=1.58.2.4&view=markup

where it starts to talk to platform-specific modules like 'nt' and
'posix'.  The 'os.py' module is a sponge that absorbs the content of
platform-specific modules in an attempt to make things look platform
independent.  *grin*

pipe() really comes from the posix/nt module, whose implementation can be
found here:

http://cvs.sourceforge.net/viewcvs.py/python/python/dist/src/Modules/posixmodule.c?view=markup


Best of wishes!
