See the limits (ulimit -a) of a process?

[Naoki]

Hi all,

    I've a question, I know you can "cat /proc/pid/environ" to get the
environment variables of a PID but is there a way to check the various
limits set when the process was spawned, for example, I want to see if
enable core dumps was set for a process (ulimit -c blah).

Any ideas?
