Detailed Description
Base class implementing the block driver interface.Member Function Documentation
| virtual int block_driver_base::reset | ( | void | ) | [inline, virtual] |
Resets the driver's state back to defaults as when powering up the machine.
Returns 0 on success. Negative error codes otherwise.
Implements block_driver.
| virtual int block_driver_base::flush_sectors | ( | void | ) | [inline, virtual] |
Flushes all currently pending operations.
That is requests to write to the backend, if the driver provides some mechanism to cache blocks. Returns 0 on success. Negative error codes otherwise.
Implements block_driver.
Reimplemented in raw_image.
