FSAL_closedir : Free the resources allocated for reading directory entries.
- Parameters:
-
| dir_descriptor | (input): Pointer to a directory descriptor filled by FSAL_opendir. |
- Returns:
- Major error codes :
- ERR_FSAL_NO_ERROR (no error)
- ERR_FSAL_FAULT (a NULL pointer was passed as mandatory argument)
- Other error codes can be returned : ERR_FSAL_IO, ...

FSAL_opendir : Opens a directory for reading its content.
- Parameters:
-
| dir_handle | (input) the handle of the directory to be opened. |
| p_context | (input) Permission context for the operation (user, export context...). |
| dir_descriptor | (output) pointer to an allocated structure that will receive directory stream informations, on successfull completion. |
| dir_attributes | (optional output) On successfull completion,the structure pointed by dir_attributes receives the new directory attributes. Can be NULL. |
- Returns:
- Major error codes :
- ERR_FSAL_NO_ERROR (no error)
- ERR_FSAL_ACCESS (user does not have read permission on directory)
- ERR_FSAL_STALE (dir_handle does not address an existing object)
- ERR_FSAL_FAULT (a NULL pointer was passed as mandatory argument)
- Other error codes can be returned : ERR_FSAL_IO, ...

FSAL_readdir : Read the entries of an opened directory.
- Parameters:
-
| dir_descriptor | (input): Pointer to the directory descriptor filled by FSAL_opendir. |
| start_position | (input): Cookie that indicates the first object to be read during this readdir operation. This should be :
- FSAL_READDIR_FROM_BEGINNING for reading the content of the directory from the beginning.
- The end_position parameter returned by the previous call to FSAL_readdir.
|
| get_attr_mask | (input) Specify the set of attributes to be retrieved for directory entries. |
| buffersize | (input) The size (in bytes) of the buffer where the direntries are to be stored. |
| pdirent | (output) Adresse of the buffer where the direntries are to be stored. |
| end_position | (output) Cookie that indicates the current position in the directory. |
| nb_entries | (output) Pointer to the number of entries read during the call. |
| end_of_dir | (output) Pointer to a boolean that indicates if the end of dir has been reached during the call. |
- Returns:
- Major error codes :
- ERR_FSAL_NO_ERROR (no error)
- ERR_FSAL_FAULT (a NULL pointer was passed as mandatory argument)
- Other error codes can be returned : ERR_FSAL_IO, ...
- Todo:
- : use NFS4_OP_VERIFY to implement a cache validator, BUGAZOMEU
