SQLITE_DBCONFIG_ENABLE_FKEY

This option is used to enable or disable the enforcement of foreign key constraints. There should be two additional arguments. The first argument is an integer which is 0 to disable FK enforcement, positive to enable FK enforcement or negative to leave FK enforcement unchanged. The second parameter is a pointer to an integer into which is written 0 or 1 to indicate whether FK enforcement is off or on following this call. The second parameter may be a NULL pointer, in which case the FK enforcement setting is not reported back.
