Typedef Documentation

typedef void(* sticker_provider_data_foreach_cb)(sticker_data_h data_handle, void *user_data)

Called to retrieve all sticker data in the sticker database.

The sticker_provider_data_foreach_all() must be called to invoke this callback function, synchronously.

Since :: 5.5

Remarks:: data_handle should not be freed and can be used only in the callback. If you want to use it outside of the callback, you need to use a clone which can be obtained sticker_data_clone().

Parameters:

[in]	data_handle	The sticker data handle
[in]	user_data	The user data passed from the foreach function

Precondition:: sticker_provider_data_foreach_all() will invoke this callback.

typedef struct sticker_provider_s* sticker_provider_h

The sticker provider handle.

Since :: 5.5

typedef void(* sticker_provider_insert_finished_cb)(sticker_error_e error, void *user_data)
