## Description

## Details

### ECalBackendSync

    typedef struct _ECalBackendSync ECalBackendSync;

### ECalBackendSyncStatus

    typedef GNOME_Evolution_Calendar_CallStatus ECalBackendSyncStatus;

### ECalBackendSyncFactoryFn ()

    ECalBackendSync*    (*ECalBackendSyncFactoryFn)         (void);
