| 26 | <para>D-Bus is a message bus system, a simple way for applications to talk
|
|---|
| 27 | to one another. D-Bus supplies both a system daemon (for events such as
|
|---|
| 28 | "new hardware device added" or "printer queue changed") and a
|
|---|
| 29 | per-user-login-session daemon (for general IPC needs among user
|
|---|
| 30 | applications). Also, the message bus is built on top of a general one-to-one
|
|---|
| 31 | message passing framework, which can be used by any two applications to
|
|---|
| 32 | communicate directly (without going through the message bus daemon).</para>
