Hi,
I'm looking at the C API and wanting to know a good way to convert
Python numeric types to native c types. For strings I've been using
PyString_AsString(v) and thats great, but I would like to do the same
for ints and floats. I have found PyFloat_AsString in the source but
it seems to be undocumented and some of the comments make me think that
I shouldn't use it but I've given it a go anyhow. It is defined in
floatobject.h as:
PyAPI_FUNC(void) PyFloat_AsString(char*, PyFloatObject *v);
and also:
PyAPI_FUNC(void) PyFloat_AsReprString(char*, PyFloatObject *v);
And I have a few questions:
Should I use these calls? And the comment that I am concerned about
from floatobject.c is:
315 /* XXX PyFloat_AsString and PyFloat_AsReprString should be
deprecated:
316 XXX they pass a char buffer without passing a length.
317 */
OK so what the caller can manage the buf len, but is there something
else I should be concerned about?
If these types of calls are the way to go, is there a call for int?
And how should I convert a PyObject to a PyFloatObject?
If this isn't a good approach, what is?
thanks,
~jason
