Data Structure Documentation

struct sector_info_t

Sector information.

Information about canned sectors. The sector data does not have to completely fill the sector. Any remainder bytes will be cleared to zero in the sector read function.

Data Fields
const uint8_t *	data	Data for the sector.
uint32_t	length	Number of bytes of data.
uint32_t	sector	Sector number.
