-** Set or clear the access authorization function.
-**
-** The access authorization function is be called during the compilation
-** phase to verify that the user has read and/or write access permission on
-** various fields of the database. The first argument to the auth function
-** is a copy of the 3rd argument to this routine. The second argument
-** to the auth function is one of these constants:
-**
-** SQLITE_CREATE_INDEX
-** SQLITE_CREATE_TABLE
-** SQLITE_CREATE_TEMP_INDEX
-** SQLITE_CREATE_TEMP_TABLE
-** SQLITE_CREATE_TEMP_TRIGGER
-** SQLITE_CREATE_TEMP_VIEW
-** SQLITE_CREATE_TRIGGER
-** SQLITE_CREATE_VIEW
-** SQLITE_DELETE
-** SQLITE_DROP_INDEX
-** SQLITE_DROP_TABLE
-** SQLITE_DROP_TEMP_INDEX
-** SQLITE_DROP_TEMP_TABLE
-** SQLITE_DROP_TEMP_TRIGGER
-** SQLITE_DROP_TEMP_VIEW
-** SQLITE_DROP_TRIGGER
-** SQLITE_DROP_VIEW
-** SQLITE_INSERT
-** SQLITE_PRAGMA
-** SQLITE_READ
-** SQLITE_SELECT
-** SQLITE_TRANSACTION
-** SQLITE_UPDATE
-**
-** The third and fourth arguments to the auth function are the name of
-** the table and the column that are being accessed. The auth function
-** should return either SQLITE_OK, SQLITE_DENY, or SQLITE_IGNORE. If
-** SQLITE_OK is returned, it means that access is allowed. SQLITE_DENY
-** means that the SQL statement will never-run - the sqlite3_exec() call
-** will return with an error. SQLITE_IGNORE means that the SQL statement
-** should run but attempts to read the specified column will return NULL
-** and attempts to write the column will be ignored.
-**
-** Setting the auth function to NULL disables this hook. The default
-** setting of the auth function is NULL.
