Serialize individual event items (see gre/io_mgr.h) into a single buffer for transmission using Storyboard IO.
Parameters: buffer The buffer that will contain the serialized data or NULL if a new buffer should be allocated event_target The name of the event target model element (screen,layer, control, render extension), or NULL to send to the default target (application level) event_name The name of the event to send, or NULL to send an empty event event_format The format description of the data (ex. "1s0 string") or NULL if no data is being sent event_data A pointer do the data to transmit, or NULL if no data is transmitted event_nbytes The number of data bytes to transmit, or NULL if no data is transmitted Returns: A buffer with the serialized data or NULL on error. It may be necessary for the internal buffer to be re-sized or re-allocated if the new data payload is larger than the previous one is being serialized. Example:
nbuffer = gre_io_serialize(nbuffer, NULL, "cluster_update",
"2u1 speed 2u1 rpm 2u1 fuel 2u1 battery 2u1 oil 2u1 odometer 2u1 trip",
&event_data, sizeof(event_data));
if(!nbuffer) {
fprintf(stderr, "Can't serialized data to buffer, exiting\n");
break;
