| memory_image (l4_sector_t size=MIN_SECTOR_NUMBER, const state_flags flags=0) | |
| virtual l4_sector_t | sectors (void) const |
| Returns the number of disk sectors the underlying medium (e.g a file) provides. | |
| virtual int | read_sectors (uint8_t *buffer, l4_sector_t sector, l4_sector_t number) |
| Reads (from disk) the specified number of sectors starting at the specified sector (inclusive) into the specified data buffer (which must be big enough). | |
| virtual int | write_sectors (uint8_t *buffer, l4_sector_t sector, l4_sector_t number) |
| Writes (to disk) the specified number of sectors starting at the specified sector (inclusive) from the specified data buffer (which must be big enough). | |
