ssize_t ReadAtV (  off_t  position,
const struct iovec *  vector,
ssize_t  count
)  [virtual]
 

Read the bytes described by iovec from location position in the storage.

Returns the number of bytes actually read, or a negative error code.

Implements IStorage.

status_t SetSize (  off_t  size  )  [virtual]
 

Set the total number of bytes in the store.

Implements IStorage.

off_t Size (   )  const [virtual]
 

Return the total number of bytes in the store.

Implements IStorage.

status_t Sync (   )  [virtual]
 

Make sure all data in the storage is written to its physical device.

Returns B_OK if the data is safely stored away, else an error code.

Implements IStorage.

ssize_t WriteAtV (  off_t  position,
const struct iovec *  vector,
ssize_t  count
)  [virtual]
 

Write the bytes described by iovec at location position in the storage.

Returns the number of bytes actually written, or a negative error code.

Implements IStorage.
