|

|

|
| -// As opposed to SharedMemIPClient, the Server object should be one for the

|
| -// 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.
