BPX4GRL (getrlimit) example

The following code fills in the rlimit structure for the calling process based on the input resource value. The resource value is set to RLIMIT_CPU. For the callable service, see getrlimit (BPX1GRL, BPX4GRL) — Get resource limits. For the data structure, see BPXYRLIM — Map the rlimit, rusage, and timeval structures. AMODE 31 callers use BPX1GRL (getrlimit) example.
