ctypes from_param() truncating 64 bit pointers to 32 bit

Hello, I wonder if I am encountering a bug in ctypes; or if I am doing things wrong? I have written a small Python class wrapping a C library, the Python class has a from_param() method which passes a raw pointer value from Python to C. When reaching C the pointer has been truncated to 32 bits.

Re: ctypes from_param() truncating 64 bit pointers to 32 bit

Thanks for answering; I rarely use ctypes You should :-) Apart from my current struggle I think ctypes is really good. and I actually don't know how this specific case works. However, you are not providing a function signature for the print_addr C function in the BugTest case, so my guess

Re: ctypes from_param() truncating 64 bit pointers to 32 bit

Ok, then take care to post proper code next time. Details can be important, especially when asking about non-obvious problems. Point taken - however the original context where the problem arose consists of several massive libraries, which would be quite impractical to post on a forum. The code

ctypes and garbage collection

to protect the Container instance from beeing garbage collected? I thought maybe the get_node() function should have something like a incref() call, and the Node.__del__() function a corresponding decref()? Or ?? Regards Joakim Hove -- http://mail.python.org/mailman/listinfo/python-list

Re: ctypes and garbage collection

I'd add an __owner field to the node, initialised with the owning container instance. I will - thank you! Joakim -- http://mail.python.org/mailman/listinfo/python-list

Encoding and norwegian (non ASCII) characters.

Hello, I am having great problems writing norwegian characters æøå to file from a python application. My (simplified) scenario is as follows: 1. I have a web form where the user can enter his name. 2. I use the cgi module module to get to the input from the user: name =

Unicode ZSI interaction ??
