Hi,
I'm working on a c-extension of python and want to create an instance of
python datetime object with a unix timestamp in c.
On the documentation site ( http://docs.python.org/c-api/datetime.html )
I found the function PyDateTime_FromTimestamp() which returns a new
reference based on an input parameter.
The description is as follows: Create and return a new datetime.datetime
object given an argument tuple suitable for passing to
datetime.datetime.fromtimestamp().
I tried out to call the function with a PyFloat_Object but the function
always returns NULL (even if I simply put in 0).
Does somebody have an example how I have to call the function or can
give a hint what kind of parameter tuple is required to get it work?
The key phrase is "argument tuple". The arguments passed to a Python
call are always a tuple, not PyFloat_Object.
You can build a tuple from the PyFloat_Object using:
Py_BuildValue("(O)", float_object)
The "(O)" says to build a tuple ("(...)") containing a single object
("O").
