Detailed Description

BlobDB front end of notification storage (BlobDBIdNotifs).

Function Documentation

notif_db_delete()

status_t notif_db_delete	(	const uint8_t *	key,
		int	key_len
	)

Delete a record from the notification database.

The key is the notification UUID.

Parameters

key	Key data.
key_len	Length of key in bytes.

Returns

S_SUCCESS on success, an error code otherwise.

notif_db_flush()

status_t notif_db_flush

(

void

)

Delete all records of the notification database.

Returns

S_SUCCESS on success, an error code otherwise.

notif_db_get_len()

int notif_db_get_len	(	const uint8_t *	key,
		int	key_len
	)

Get the length of a record in the notification database.

The key is the notification UUID.

Parameters

key	Key data.
key_len	Length of key in bytes.

Returns

Length of the value in bytes, 0 if not found, or a negative error code.

notif_db_init()

void notif_db_init

(

void

)

Initialize the notification database.

notif_db_insert()

status_t notif_db_insert	(	const uint8_t *	key,
		int	key_len,
		const uint8_t *	val,
		int	val_len
	)

Insert or replace a record in the notification database.

The key is the notification UUID and the value a serialized timeline item. A new notification is stored and announced; for an existing one only the status bits are updated. New notifications that already carry status bits are ignored.

Parameters

key	Key data.
key_len	Length of key in bytes.
val	Value data.
val_len	Length of val in bytes.

Returns

S_SUCCESS on success, an error code otherwise.

notif_db_read()

status_t notif_db_read	(	const uint8_t *	key,
		int	key_len,
		uint8_t *	val_out,
		int	val_out_len
	)

Read a record from the notification database.

Not implemented: returns S_SUCCESS without writing to val_out.

Parameters

	key	Key data.
	key_len	Length of key in bytes.
[out]	val_out	Buffer for the value.
	val_out_len	Size of val_out in bytes.

Returns

S_SUCCESS on success, an error code otherwise.
