| /** |
| * array_size - routine for safely deriving the size of a visible array. |
| * |
| * This provides a simple ARRAY_SIZE() macro, which (given a good compiler) |
| * will also break compile if you try to use it on a pointer. |
| * |
| * This can ensure your code is robust to changes, without needing a gratuitous |
| * macro or constant. |
| * |
| * Example: |
| * // Outputs "Initialized 32 values" |
| * #include <ccan/array_size/array_size.h> |
| * #include <stdlib.h> |
| * #include <stdio.h> |
| * |
| * // We currently use 32 random values. |
| * static unsigned int vals[32]; |
| * |
| * int main(void) |
| * { |
| * unsigned int i; |
| * for (i = 0; i < ARRAY_SIZE(vals); i++) |
| * vals[i] = random(); |
| * printf("Initialized %u values\n", i); |
| * return 0; |
| * } |
