- * alignof - ALIGNOF() macro to determine alignment of a type.
- *
- * Many platforms have requirements that certain types must be aligned
- * to certain address boundaries, such as ints needing to be on 4-byte
- * boundaries. Attempting to access variables with incorrect
- * alignment may cause performance loss or even program failure (eg. a
- * bus signal).
- *
- * There are times which it's useful to be able to programatically
- * access these requirements, such as for dynamic allocators.
- *
- * Example:
- * #include <stdio.h>
- * #include <stdlib.h>
- * #include <ccan/alignof/alignof.h>
- *
- * int main(int argc, char *argv[])
- * {
- * char arr[sizeof(int)];
- *
- * if ((unsigned long)arr % ALIGNOF(int)) {
- * printf("arr %p CANNOT hold an int\n", arr);
- * exit(1);
- * } else {
- * printf("arr %p CAN hold an int\n", arr);
- * exit(0);
- * }
- * }
