device_read_t partition_struct::device_read

The function which reads data from the partition.

Note:

The offset given to this function is relative to the whole disk, not to the start of the partition.

device_read_interval_t partition_struct::device_read_interval

The function which repeatedly reads a constant amount of data from the partition.

Note:

The offset given to this function is relative to the whole disk, not to the start of the partition.
