|
|
* The #OstreeRemote structure represents the configuration for a single remote
|
|
* repository. Currently, all configuration is handled internally, and
|
|
* #OstreeRemote objects are represented by their textual name handle, or by an
|
|
* opaque pointer (which can be reference counted if needed).
|
|
*
|
|
* #OstreeRemote provides configuration for accessing a remote, but does not
|
|
* provide the results of accessing a remote, such as information about what
|
|
* refs are currently on a remote, or the commits they currently point to. Use
|
|
* #OstreeRepo in combination with an #OstreeRemote to query that information.
|
|
