If the xDelUser variable is set to a non-NULL value, then after the custom r-tree query has finished running SQLite automatically invokes it with the value of the pUser variable as the only argument. In other words, xDelUser may be set to a destructor function for the pUser value. | > > > > | 398 399 400 401 402 403 404 405 406 407 408 409 | invocations of the callback within the same custom r-tree query (for example, a pointer to a complicated data structure used to test for region intersection).
