How can i calculate percentage cpu and memory usage in linux through C code.

I want to know cpu and memory usage for whole system

I'm not sure if this is the way you're intending, but you could run the "system()" function in your program with the "lscpu" command:



system("lscpu | grep -E \"(MHz|family|MIPS|L1d|l1i|L2|L3|stepping)\"");

I hope this helps!
