Hi, I'll admit right off that I haven't followed all of the extended buffer protocol discussions - I have no real need for anything much beyond the existing "here's a blob of memory" level of functionality.
I have skimmed (briefly, I'll admit!) the pre-PEP, but I've found it extremely difficult to find a simple example of the basic (in my view) use case of an undifferentiated block of bytes. Can I suggest that the following uses would be the significant majority of buffer protocol uses - they are certainly going to be the basic transitional case from the existing protocol - and deserve to be singled out in the PEP with some description or (better) pseudo-code examples. If they are already there, I apologise, but I did look, and got bogged down in the more sophisticated stuff - so they probably need making more visible. 1. (Producer) I have a block of memory in my C extension and I want to expose it as a simple contiguous block of bytes to Python. 2. (Consumer) I want to get at a block of memory exposed as a buffer. I am only interested in, and only support, viewing a buffer as a block of contiguous bytes. I expect most if not all extensions to be able to provide such a view. I'd hope these 2 cases are pretty simple to code, but I'd like to see that made explicit in the PEP. unsophisticated-ly y'rs Paul. _______________________________________________ Python-Dev mailing list Python-Dev@python.org http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
