#define ARRAY_SIZE

(

arr

)

(sizeof(arr) / sizeof((arr)[0]))

Canonical macro-based ARRAY_SIZE. Use with care for side effectes!

#define container_of	(		ptr,
			type,
			mem
	)		((type*) (((char*)(ptr)) - offsetof(type, mem)))

Converts pointer to a member of a structure to the pointer to the structure.

Usage:

struct my_work_t {
  struct work_t base_work;
  int my_data;
};
void my_work_cb(struct work_t *work) {
  struct my_work_t *my_work = container_of(work, struct my_work_t, base_work);
  my_work->my_data++;
}

Parameters

ptr	pointer to the member of the structure
type	type name of the structure
mem	name of the memeber of the structure

Returns

pointer to the structure
