Is it possible to monitor the memory without using any system call in Linux , C language?

Question

Is it possible to monitor the memory (memory watcher) without using any system call in Linux , C language? Am beginner in C and i have searched a lot about it but i couldn't find any solution except using system calls like:

meminfo , Top system calls.

So the question is, can i access the memory and get information about the process and the usage of memory for each without any system call? please help.

Answer 1

On Linux, you can get that information from reading files in /proc . Reading files does require making system calls, but you don't have to worry about that since C library functions like open() and read() will make those system calls for you.

Read up on the /proc filesystem, experiment with it by cat ting files from your shell, then when you are ready to use it in C, Google for a tutorial on how to read files in C using the standard library.
