CTL_STATUS_t ctl_xively_datapoint_delete(CTL_XIVELY_DATASTREAM_t *stream, const CTL_XIVELY_TIMESTAMP_t *stamp);
ctl_xively_datapoint_delete sends a request to the Xively API to delete the datapoint with timestamp stamp from the datastream self in the feed that the datastream is registered to. This function does not remove any data from the local datastream buffer: it is a direct request using a live connection to the Xively server.
ctl_xively_datapoint_delete returns a standard status code.
