When I call a custom aggregate function on an empty table T, e.g., `select myaggr(A) from T`, the sqlite3_aggregate_context() call in the xFinal callback does not return zeroed out memory, but a block of seemingly uninitialized memory. Is that expected? If so, how do I know that the xStep callback has not been called?The code looks like this: typedef struct Aggr Aggr; struct Aggr { Value value; uint32_t count; }; static void myaggrStep(sqlite3_context* ctx, int argc, sqlite3_value** argv) { Aggr* sum = (Aggr*)sqlite3_aggregate_context(ctx, sizeof(Aggr*));
Oh dear. Never mind, I have just noticed the spurious pointer. Sorry for the noise, Life. _______________________________________________ sqlite-users mailing list [email protected] http://mailinglists.sqlite.org/cgi-bin/mailman/listinfo/sqlite-users
