+This routine registers a callback. The callback is invoked for each attempt to
+access a column of a table in the database. The callback should return
+\constant{SQLITE_OK} if access is allowed, \constant{SQLITE_DENY} if the entire
+SQL statement should be aborted with an error and \constant{SQLITE_IGNORE} if
+the column should be treated as a NULL value. These constants are available in
+the \module{sqlite3} module.
+
+The first argument to the callback signifies what kind of operation is to be
+authorized. The second and third argument will be arguments or \constant{None}
+depending on the first argument. The 4th argument is the name of the database
+("main", "temp", etc.) if applicable. The 5th argument is the name of the
+inner-most trigger or view that is responsible for the access attempt or
+\constant{None} if this access attempt is directly from input SQL code.

+Please consult the SQLite documentation about the possible values for the first
+argument and the meaning of the second and third argument depending on the
+first one. All necessary constants are available in the \module{sqlite3}
+module.
