class InMemoryNdm

Creates a new volume. Note that multiple volumes are not supported.

|ftl_volume| (if provided) will be notified with the volume details.

Returns an error string, or nullptr on success.

The options in raw_nand should be prepopulated as desired, and optionally

page_data and page_oob. page_size and oob_size should have the

corresponding sizes to match with the sizes used in raw_nand, where

page_size is the size of volume pages and oob_size is the size of the

corresponding out of band data used by the FTL. max_bad_blocks is the

maximum number of bad blocks to support in the ndm, more means a smaller

overall volume as spare blocks at the end of the volume are set aside to

account for this.

Reads |page_count| pages starting at |start_page|, placing the results on

|page_buffer| and |oob_buffer|. Either pointer can be nullptr if that

part is not desired.

Returns kNdmOk, kNdmUncorrectableEcc, kNdmFatalError or kNdmUnsafeEcc.

Performs driver initialization. Returns an error string, or nullptr on

success.

Destroy the volume created with Attach(). Returns true on success.

Returns whether the block containing |page_num| was factory-marked as bad.

Returns kTrue, kFalse or kNdmError.

Writes |page_count| pages starting at |start_page|, using the data from

|page_buffer| and |oob_buffer|.

Returns kNdmOk, kNdmError or kNdmFatalError. kNdmError triggers marking

the block as bad.

Erases the block containing |page_num|.

Returns kNdmOk or kNdmError. kNdmError triggers marking the block as bad.

Returns whether a given page is empty or not. |data| and |spare| store

the contents of the page.
