create a ramdisk in C++ on linux

Question

I need to make a ramfs an mount it to an directory in linux using c++. I want to make it like a user (no sudo).

I need to call an application on a file that i created and it will be often. Writing it to HDD is very slow.

I found just:

system("mkdir /mnt/ram");
system("mount -t ramfs -o size=20m ramfs /mnt/ram");

but that is not good. I want to be a regular user, and command mount can be called just as root. what can i do?

For a userspace ramfs solution, you can use python-fuse-ramfs.
