Some application may need to access a pinned map which is not created by bcc. This example shows how to incorporate such maps with C++ APIs. Basically, the application needs to create a TableStorage and pre-populate it with pinned map before calling BPF constructor. The bpf program defines this pinned map as an "extern" map.
