fsal_op_context_t p_context,
fsal_dir_t dir_desc,
fsal_attrib_list_t dir_attributes 
)

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)

)

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 :

  • 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)
