-// IPC transport implementation that uses shared memory. |
-// This is the server side |
-// |
-// The server side has knowledge about the layout of the shared memory |
-// and the state transitions. Both are explained in sharedmem_ipc_client.h |
-// |
-// As opposed to SharedMemIPClient, the Server object should be one for the |
-// entire lifetime of the target process. The server is in charge of creating |
-// the events (ping, pong) both for the client and for the target that are used |
-// to signal the IPC and also in charge of setting the initial state of the |
-// channels. |
-// |
-// When an IPC is ready, the server relies on being called by on the |
-// ThreadPingEventReady callback. The IPC server then retrieves the buffer, |
-// marshals it into a CrossCallParam object and calls the Dispatcher, who is in |
-// charge of fulfilling the IPC request. |
