Support for File Mapped Memory?

[wysota]

Qt is a platform independent library and I think that in this particular situation memory mapping is different on different platforms, so it'd be a bit hard to provide a solution that work on all platforms in a simmilar way. Remember that someone has to write all the routines and there are surely more urgent things to do than to provide portable memory mappings.

Qt doesn't have to do everything, you can always use platform dependent solutions.

Well I appreciate the response but I'm not sure I really agree.

Ok, so it sounds like my only option then is to just write my own class to handle this. It looks like I can borrow some code from the link that was provided to implement it on linux, and I already know how to do it in win32. Assuming that I can get it working on linux, is it safe to assume that the same code will also work on Mac OS/X (Darwin), or am I going to have to go digging around in the Carbon API? For that matter, is Mac really even separate platform anymore or is it just linux with a proprietary window manager?

It's not safe to assume anything - I didn't even compile the code. In theory it should run but I give no warranty. mmap() is POSIX compliant, so it should work on all POSIX systems (notice the should word in both cases).
