Using C++ Boost memory mapped files to create disk-back data structures

Question

I have been looking into using Boost.Interprocess to create a disk-backed data structure. The examples on Boost Documentation (http://www.boost.org/doc/libs/1_41_0/doc/html/interprocess.html) are all for using shared memory even though they mention that memory mapped files can also be used. I am wondering whether anyone here has used memory mapped files? Any publicly available code samples to get started (say, a memory mapped file backed map or set)?

You might take look at stldb project that's being actively discussed on boost mail list. It tries to build an ACID database on top of boost::interprocess.

Thanks for the pointer Nikolai! I haven't heard of stldb (though have worked with stxxl in the past); I checked out the code and had a peripheral look it seems they do use memory mapped files to back data structures. Need to explore more before I can be definite about this. – Epirogeny
