I don't know how to get the limit but I do know how to get the count of
handles currently in use. I am using the C library that java sigar
employs. I can get the number of file handles a process uses by calling
sigar_proc_fd_get. The structure this fills in has a member total, which
is the file handle count.

Obtaining maximum configured open file descriptors of the current user
I want to obtain the maximum available open file descriptors of the
current user in a linux OS using sigar (ulimit -n).
I tried using the Ulimit class but it seems to provide me with the hard
limit which is I think the machine maximum configured open file
descriptors and not the current user. If I ran ulimit -n in shell I get a
different number then what sigar is showing (a lower number) and I need
the result to be the ulimit -n which is the soft limit (current user
limit). Obviously I want this to be cross OS as much as possible otherwise
I would not be using Sigar.
I also looked at Sigar.getResourceLimit().getOpenFilesCur() and
getOpenFileMax() but it also returns the hard limit.
Additionally, is there any other way to obtain the currently used open
file descriptors of the current user in one command other then going over
all the existing processes pids in a loop and accumulating
