Use a memory mapped file. You can use pointer operations on the file
contents. Whether a file page is actually on disk or in memory becomes
the operating system concerns.

Note that memory-mapped files are beyond the scope of Standard C.
They are also system-specific, and not all systems support them.
If you do go that route, I would suggest at least putting wrappers
around the system-specific functions to allow easier porting to
other systems which support memory-mapped files differently.

Or find a toolkit that already does this.
I use ACE, but that is C++.
I seem to remember seeing similar things for C.
