Typedef Documentation

typedef void(* watchface_complication_provider_update_requested_cb)(const char *provider_id, const char *req_appid, watchface_complication_type_e type, const bundle *context, bundle *share_data, void *user_data)

Called when a watchface complication requests data update.

Watchface application which sends an update request will receive share_data through watchface_complication_updated_cb()'s data parameter after this callback is finished.

Since :: 5.0

Remarks:: The share_data should not be released.

Parameters:

[in]	provider_id	The id of the provider The provider_id can be used only in the callback. To use outside, make a copy.
[in]	req_appid	The name of the watchface that update request The req_appid can be used only in the callback. To use outside, make a copy.
[in]	type	Complication Type
[in]	context	The data set in the setting app for the provider The context can be used only in the callback. To use outside, make a copy.
[in]	share_data	The data to update. This data will be shared with watchface application. The share_data is managed by the platform and will be released after this callback is finished.
[in]	user_data	The user data passed from the callback function
