|
|
* Kernel object representing the server endpoint of an IPC session. Sessions are the basic CTR-OS
|
|
* primitive for communication between different processes, and are used to implement service calls
|
|
* to the various system services.
|
|
*
|
|
* To make a service call, the client must write the command header and parameters to the buffer
|
|
* located at offset 0x80 of the TLS (Thread-Local Storage) area, then execute a SendSyncRequest
|
|
* SVC call with its ClientSession handle. The kernel will read the command header, using it to marshall
|
|
* the parameters to the process at the server endpoint of the session. After the server replies to
|
|
* the request, the response is marshalled back to the caller's TLS buffer and control is
|
|
* transferred back to it.
