I had just realized from reading your last message that you were trying
to write server-side functions, and reading the client-side
documentation to do so :-(. The server-side stuff is really not the
same API at all, though it tends to use the same function names.
In general, you have to be prepared to read the source code when writing
server-side stuff.
