## Functions

### gcab_cabinet_new ()

    GCabCabinet *
    gcab_cabinet_new (void);

Create a new GCabCabinet object to read or create a Cabinet archive.

#### Returns

a new GCabCabinet

### gcab_cabinet_load ()

                       GError **error);

Load a cabinet archive.

#### Parameters

cabinet | a GCabCabinet |
stream | a GInputStream |
cancellable | optional GCancellable object, `NULL` to ignore. | [allow-none]
