Subject: cleaning up in UDF's (user-defined functions)

I appended an excerpt from the docs... IIUC, if I make
a DSQL call from a UDF (written in C), and there's a
transaction abort caused by that command, then my
function is never called back. How do I cleanup any
resources the function allocated if this is the case?

I'm not even sure how I could NOTIFY clients, since
the transaction aborted.

thanks!

Note that if during the execution of a procedure the
transaction is aborted because of an error in a
command, then control will not be returned to your
procedure. Rather, all work will be rolled back and
the server will wait for the next command from the
client. A related restriction is the inability to
execute BEGIN, COMMIT, and ROLLBACK (transaction
control statements) inside a procedure. Both of these
restrictions will probably be changed in the future.
