| 17:56 | Fix an incorrect type signature for the loadable extension pointer for sqlite3_result_pointer(). (Closed-Leaf check-in: 0bd7875b user: drh tags: bind-pointer) | |
| 17:54 | Add the three new pointer interfaces to the loadable extension mechanism. Update sqlite3_value_subtype() documentation to remove the statement about it not being used internally. (check-in: e5a51803 user: drh tags: bind-pointer) | |
| 17:48 | Update the FTS3 extension to use sqlite3_result_pointer() and sqlite3_value_pointer() for passing FTS3 cursor objects from the table into functions such as snippet(). (check-in: 0fa2e170 user: drh tags: bind-pointer) | |
