getrlimit(p1) public

Gets the resource limit of the process. cur_limit means current (soft) limit and max_limit means maximum (hard) limit.

resource indicates the kind of resource to limit: such as Process::RLIMIT_CORE, Process::RLIMIT_CPU, etc. See <a href="/ruby/Process/setrlimit/class">Process.setrlimit</a> for details.

cur_limit and max_limit may be Process::RLIM_INFINITY, Process::RLIM_SAVED_MAX or Process::RLIM_SAVED_CUR. See <a href="/ruby/Process/setrlimit/class">Process.setrlimit</a> and the system getrlimit(2) manual for details.
