Question about long IPC implementation in Genode implementation

[yu000013]

Thank you for your reply!


I looked through the references and got a general idea of IPC in Genode.


I guess my previous understanding of "long IPC" already includes the "shared-memory" method used in the up-to-date Genode framework.


Now I'm looking for the shared memory invocation in Genode source codes and hoping to understand this mechanism in the code level.


Thank you very much!
