Creating arrays (builtin) in C Extensions

[iwl]

Hello,

there is an builtin documented array module in phyton,
but no documentation how such an array can be
created in C-Extension functions.
So I have to use Lists at time, but this is I think
inefficient with large data sets.

Is there some interface aviable which I can link to my
Programm without any change to standard python?

I would guess you create an array from C the same way you create any other
Python objects. So call PyImport_ImportModule to get the array module, get
its 'array' attribute with PyObject_GetAttrString then call PyObject_New to
create your array.

There is documentation on how to set the data in the array. See
http://docs.python.org/api/bufferObjects.html
