External interface for storing/loading Kaa status.

Function Documentation

void ext_status_delete ( void  )

Deletes a status storage.

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

Called on Kaa startup to restore the persisted state.

Fetch persisted state to buffer and provide a valid size of it in buffer_size. If *buffer == NULL or *buffer_size == 0 Kaa library will use default values. Set *needs_deallocation = true if buffer should be deallocated by Kaa, false otherwise.

Parameters
[out]bufferPointer to buffer which should be filled with Kaa status data.
[out]buffer_sizePointer to buffer's size.
[out]needs_deallocationIndicates if the Kaa library should deallocate buffer by itself.
void ext_status_store ( const char *  buffer,
size_t  buffer_size 
)

Called when Kaa is ready to persist its state.

Parameters
[in]bufferValid pointer to buffer which contains the current Kaa status data.
[in]buffer_sizeThe buffer's size.
