→Ports
Ports are interfaces for managing multiple client sessions to the same high-level server. Ports are created through svcCreatePort, and can be global or private. A global port is created by passing a name for the port to svcCreatePort. Clients can start IPC sessions to global ports by connecting to the port using svcConnectToPort, passing the desired port name. If the port is private, it is not possible to create a session through svcConnectToPort - sessions can only be created if one has a handle to the port itself, obtained from the call to svcCreatePort. When a client wishes to connect to a port (i.e. create a session), the server must accept the new session using svcAcceptSession. The kernel notifies the server whenever a new session is incoming via the server's port handle. The server can wait for this notification through svcWaitSynchronization or svcReplyAndReceive.

The two global ports usually found on retail are "srv:" ([[Services|service manager]]) and "err:f" ([[ErrDisp]]).
