I am looking for a vala example using GData.  I keep getting errors on
the one I have found.  I want to access documents and spreadsheets.

https://code.launchpad.net/~doctormo/.../gdata-vala-experiments

I posted on the vala mailing list and it was suggested that I submit a bug.

 I get the following error running the code snippet I
found as is.

gdata_experiments.vala:26.24-26.75: error: 1 missing arguments for
`GData.DocumentsFeed GData.DocumentsService.query_documents
(GData.DocumentsQuery query, GLib.Cancellable cancellable,
GData.QueryProgressCallback progress_callback, void*
progress_user_data)'
           var feed = this.gdocs.query_documents (query, cancel, () => {});

I looked at valadoc api documentation and it indicates an additional
parameter of type void* (not sure what this is exactly - gpointer
according to the header file), so I add a null as the last parameter
and then I get the following error.

gdata_experiments.c:134:3: error: too many arguments to function
