       For the shell command ulimit, see bash(1).

       The ulimit call will get or set some limit for the current process.  The cmd argument can have one of the following values.

       3      (Not implemented for Linux.)  Return the maximum possible address of the data segment.

       4      (Implemented but no symbolic constant provided.)	Return the maximum number of files that the calling process can open.

RETURN VALUE

       On success, ulimit returns a nonnegative value.	On error, -1 is returned, and errno is set appropriately.
