How to build the Python Numeric double array in a C extension module?

[Wojciech Zabolotny]

Hi All,

I have to write a C extension module for DSP with Python. One of its
function will be to read the signal samples from DAQ system or from
disk file. To do it efficiently, I have to be able to build an float
or double Python Numeric array in my C function.
The Py_BuildValue function does not seem to be able to do it,
or the format specifiers given in my /usr/doc/python/html/ext/buildValue.html
are not complete.
In the Python Numeric doc I couldn't find anything about writing C
extensions working with this module.

 How to solve my problem, or where to find the more detailed info about
interfacing the Python Numeric module?
