+/**
+ * container_of - routine for upcasting
+ *
+ * It is often convenient to create code where the caller registers a pointer
+ * to a generic structure and a callback. The callback might know that the
+ * pointer points to within a larger structure, and container_of gives a
+ * convenient and fairly type-safe way of returning to the enclosing structure.
+ *
+ * This idiom is an alternative to providing a void * pointer for every
+ * callback.
+ *
+ * Example:
+ * #include <stdio.h>
+ * #include <ccan/container_of/container_of.h>
+ *
+ * struct timer {
+ * void *members;
+ * };
+ *
+ * struct info {
+ * int my_stuff;
+ * struct timer timer;
+ * };
+ *
+ * static void register_timer(struct timer *timer)
+ * {
+ * //...
+ * }
+ *
+ * static void my_timer_callback(struct timer *timer)
+ * {
+ * struct info *info = container_of(timer, struct info, timer);
+ * printf("my_stuff is %u\n", info->my_stuff);
+ * }
+ *
+ * int main(void)
+ * {
+ * struct info info = { .my_stuff = 1 };
+ *
+ * register_timer(&info.timer);
+ * // ...
+ * return 0;
+ * }
