Memory usage of current process in C

Question

I need to get the memory usage of the current process in C. Can someone offer a code sample of how to do this on a Linux platform?

I\'m aware of the cat /proc/

Answer 1

You can always just open the 'files' in the /proc system as you would a regular file (using the 'self' symlink so you don't have to look up your own pid):

FILE* status = fopen( "/proc/self/status", "r" );

Of course, you now have to parse the file to pick out the information you need.
