Creates a new BookClient for source
.
If an error occurs, the function will set error
and return false
.
Unlike with BookClient, there is no need to call open_sync after obtaining the BookClient.
The wait_for_connected_seconds
argument had been added since 3.16, to let the caller decide how long to wait for the backend
to fully connect to its (possibly remote) data store. This is required due to a change in the authentication process, which is fully
asynchronous and done on the client side, while not every client is supposed to response to authentication requests. In case the backend
will not connect within the set interval, then it is opened in an offline mode. A special value -1 can be used to not wait for the
connected state at all.
For error handling convenience, any error message returned by this function will have a descriptive prefix that includes the display name
of source
.
