The thing is /proc/[pid]/status is a text file. So your fread is copying text into the struct status - so everything will look like gibberish.

You could read the status file line by line or you could use the /proc/[pid]/stat file which contains the same information on a single line (status is for human consumption while stat is for program consumtion). To get the process id (or any other information) you would just have to tokenize that single line.
