pub unsafe extern "C" fn Dart_ServiceSendDataEvent(

Sends a data event to clients of the VM Service.

A data event is used to pass an array of bytes to subscribed VM Service clients. For example, in the standalone embedder, this is function used to provide WriteEvents on the Stdout and Stderr streams.

If the embedder passes in a stream id for which no client is subscribed, then the event is ignored.

\param stream_id The id of the stream on which to post the event.

\param event_kind A string identifying what kind of event this is. For example, ‘WriteEvent’.

\param bytes A pointer to an array of bytes.

\param bytes_length The length of the byte array.

\return NULL if the arguments are well formed. Otherwise, returns an error string. The caller is responsible for freeing the error message.
