PyArg_Parse vs. PyArg_ParseTuple?

[Grant Edwards]

I was hacking on socketmodule.c, and noticed that in some
places PyArg_Parse() is used to convert Python data to C data,
and in other spots PyArg_ParseTuple() is used.  

In order to get one line to do what I wanted, I had to change
from PyArg_Parse to PyArg_ParseTuple.  It seems to work the way
I expect.

I found the documentation on PyArg_ParseTuple(), but I can't
find any documentation on PyArg_Parse(). So I'm not 100% sure
that what I did was "safe".  What is the difference between
PyArg_Parse and PyArg_ParseTuple?
