done	bufinfo_t *	devinfo_t *	fileinfo_t *
wait-start	bufinfo_t *	devinfo_t *	fileinfo_t *
wait-done	bufinfo_t *	devinfo_t *	fileinfo_t *

Each io probe has arguments consisting of a pointer to a bufinfo_t structure, a pointer to a devinfo_t, and a pointer to a fileinfo_t. These structures are described in greater detail in the following section.
