This isn't an SQLite problem; it's a C problem. You need to make a
C-style closure: function plus pointer to structure of persistent
data. Define:
struct write_closure {
mystructure *next;
};
or whatever, then put a struct write_closure on the stack and pass a
pointer to that. Then you can mutate the members of the closure
structure (in this case, have each callback invocation increment the
next-pointer).
