fetch()

static nserror fetch ( nsurl *  url, enum backing_store_flags  flags, uint8_t **  data_out, size_t *  datalen_out  )

finalise()

static nserror finalise ( void  )

Definition at line 34 of file no_backing_store.c.

References NSERROR_OK.

initialise()

static nserror initialise ( const struct llcache_store_parameters *  parameters )

static

Definition at line 29 of file no_backing_store.c.

References NSERROR_OK.

invalidate()

static nserror invalidate ( nsurl *  url )

static

Definition at line 55 of file no_backing_store.c.

References NSERROR_NOT_FOUND.

release()

static nserror release ( nsurl *  url, enum backing_store_flags  flags  )

static

release a previously fetched or stored memory object.

if the BACKING_STORE_ALLOC flag was used with the fetch or store operation for this url the returned storage is unreferenced. When the reference count drops to zero the storage is released.

Parameters

	url	The url is used as the unique primary key to invalidate.
[in]	flags	The flags to control how the object data is released.

Returns

NSERROR_OK on success or error code on faliure.
