** Open an RBU handle to perform an RBU vacuum database file zTarget.
|

** Open an RBU handle to perform an RBU vacuum on database file zTarget.
|
||||
** An RBU vacuum is similar to SQLite's built-in VACUUM command, except
|
||||
** that it can be suspended and resumed like an RBU update.
|
||||
**
|
||||
** The second argument to this function, which may not be NULL, identifies
|
||||
** a database in which to store the state of the RBU vacuum operation if
|
||||
** it is suspended. The first time sqlite3rbu_vacuum() is called, to start
|
||||
** an RBU vacuum operation, the state database should either not exist or
|
||||
** be empty (contain no tables). If an RBU vacuum is suspended by calling
|
||||
** sqlite3rbu_close() on the RBU handle before sqlite3rbu_step() has
|
||||
** returned SQLITE_DONE, the vacuum state is stored in the state database.
|
||||
** The vacuum can be resumed by calling this function to open a new RBU
|
||||
** handle specifying the same target and state databases.
|
||||
**
|
||||
** This function does not delete the state database after an RBU vacuum
|
||||
** is completed, even if it created it.
|
||||
**
|
||||
** As with sqlite3rbu_open(), Zipvfs users should rever to the comment
|
||||
** describing the sqlite3rbu_create_vfs() API function below for
|
||||
** a description of the complications associated with using RBU with
|
||||
** zipvfs databases.
