Hi
I want to map 64 bit integers from C to python. I must use Python 2.2
BUT There is no support for 64 bits integers in Python2.2 (Supported
in 2.5).
Now the problem is that I have these four variables:
unit32_t a,b,c;
uint64_t w,x,y,z;
I use this funtion to map values:
Py_BuildValue( "(lllllll)", a,b,c,w,x,y,z );
As I access 32 bit values in Python it works fine BUT 64 bit intergers
in Pythong give garbage values . I think there may be a case of
overflow when 64 bit values in C are mapped to python.
Any Suggestions?
pywin32 had this requirement, and although support was recently removed,
if you look at:
http://pywin32.cvs.sourceforge.net/viewvc/pywin32/pywin32/win32/src/PyLARGE_INTEGER.cpp?revision=1.11&view=markup
you should find routines that work without 'longlong' support in Python
itself.
Cheers,
Mark
