First, let me say thanks for answering... > What have you gathered from people who have gone before? googling python > vxworks gives about 50k hits
And chances are, they will all be unrelated to my question. WRS uses python for various IDE scripting needs, but they do not use it on their own platform. Before I ported Python to VxWorks, AFAIK, it didn't exist on that platform. > our post does not have enough info about your environment, That's because I'm not asking someone to specifically tell me how to do it on VxWorks. This is because I'm sure a VxWorks specific solution does not exist. I'm asking about the best road to take given a generic python environment. I added the extra information just in case someone had some insight of the platform and python. If a generic answer does not exist then I'm sure I'll have to craft something my self...which is also part of what I'm trying to determine. The question is very simple...aside from mmap, does there exist any pre-existing facilities in python to which I can pass an address and an length and have the associated chunk of memory exposed to python while using an existing type, which does not attempt to malloc and copy? Unless you have a specific answer which uses vxWorks specific facilities, the fact that it's on VxWorks is strictly informational. > Once you have an access-providing object, what kind of access do you require? It doesn't really matter. It just so happens that it's read only access, but I can't see how it matters. Later on, it may require write access too. I simply need to access the binary data byte for byte. > What modules/libraries do you have to give you access now from python to the > vxworks environment? As I said before, I have a chuck of memory, to which I have a pointer. I know the length of the memory. I would like to obtain acecss to the chuck of memory. Based on everything I'm seeing, it seems the answer is a custom module, all the way; which I can probably base the mmap module. Sorry for any confusion my original question may of created. I was rushed when I posted it. Hopefully this posting will be more clear as to my intentions and needs. Sincerely, Greg -- http://mail.python.org/mailman/listinfo/python-list
