How can I detect hung processes in Linux using C?
c, linux
Solution
Under linux the way to do this is by examining the contents of /proc/[PID]/* a good one-stop location would be /proc/*/status. Its first two lines are:
Name: [program name] State: R (running)
Of course, detecting hung processes is an entirely separate issue.
/proc//stat is a more machine-readable format of the same info as /proc//status, and is, in fact, what the ps(1) command reads to produce its output.
