#2786 — Re: how to save a file to memory rather to disk?

You could try using shared memory, by looking into the functions
mmap() and shmget(). However, note that it's quite a low level
approach. Also, they are not Standard C++ functions, they are POSIX's.
If you have specific OSs in mind, such as Linux, then it's an
alternative. Just don't expect the portability to be the same as using
the filesystem.

The OP could try using Boost.Interprocess library if he/she wants to use 
a portable shared memory approach.
