RAM access using a c program
 

hello and Namastey!
i am developping a tool for freeing up unused ram in linux ubuntu.
i am finding something through which i would be able to access the ram of my pc using my c program.
please tell me if there is a way to do so.
is there any system call available? or i have to do programming at kernel level? (i mean do i have to compile the whole kernel?)

You can examine memory using the /proc/kcore handle, assuming that you don't care about the physical memory address.

However, you will find that Linux already makes use of as much RAM as it can; if it isn't in use by applications, it will be used for disk caching.

thank you very much..
i read the utilities provided by /proc
