|
// point for socket management. libipc users can register sockets via
|
||
|
|
// ipc_add_fd allowing them to trigger an event, so events unrelated
|

// to libipc are managed the same way.

// websocket proxy allowing libipc services to be accessible online.

|
||
|
|
// can be bound together, each message coming from one end will be
|

|
// automatically transfered to the other socket and a Switch event
|

|
|
// will be triggered.

// ipc daemon (ipcd) to locate the service and establish a connection
|

// to it. This is a lookup.
