| michael@0 | 9 | * The nsIServiceManager manager interface provides a means to obtain |
| michael@0 | 10 | * global services in an application. The service manager depends on the |
| michael@0 | 11 | * repository to find and instantiate factories to obtain services. |
| michael@0 | 12 | * |
| michael@0 | 13 | * Users of the service manager must first obtain a pointer to the global |
| michael@0 | 14 | * service manager by calling NS_GetServiceManager. After that, |
| michael@0 | 15 | * they can request specific services by calling GetService. When they are |
| michael@0 | 16 | * finished they can NS_RELEASE() the service as usual. |
| michael@0 | 17 | * |
| michael@0 | 18 | * A user of a service may keep references to particular services indefinitely |
| michael@0 | 19 | * and only must call Release when it shuts down. |
