No. These are all identical: const int foo[]; int const foo[]; const int const foo[]; const const const int const const const foo[]; If it were a pointer, then there would be a difference between these: const int *foo; (pointed-to data is const) int *const foo; (pointer itself is const) const int *const foo; (both are const) ...but still there's no distinction between these: const int *foo; const int const *foo; -Scott _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
