Function Documentation

void ext_configuration_read	(	char **	buffer,
		size_t *	buffer_size,
		bool *	needs_deallocation
	)

Called on Kaa startup to restore the persisted configuration data (if present).

Fetch configuration data to buffer and provide a valid size of it in buffer_size. If *buffer == NULL or *buffer_size == 0 then there is no persisted configuration yet. Set *needs_deallocation = true if buffer should be deallocated by Kaa, false otherwise.

Parameters

[out]	buffer	Pointer to buffer which should be filled with Kaa configuration data.
[out]	buffer_size	Pointer to buffer's size.
[out]	needs_deallocation	Indicates if the Kaa library should deallocate buffer by itself.

void ext_configuration_store	(	const char *	buffer,
		size_t	buffer_size
	)

Called when Kaa is ready to persist configuration data.

Parameters

[in]	buffer	Valid pointer to buffer which contains the current Kaa configuration data.
[in]	buffer_size	The buffer's size.
