deltapub-correlation

Including the basic AMPS library:

#include <amps/ampsplusplus.hpp>

Constructing the command:

AMPS::Command cmd(AMPS::Message::Command::DeltaPublish);

// Set the topic and data (required)
cmd.setTopic(topic).setData(data);

// Set the correlation ID
cmd.setCorrelationId(cross_ref);

The command can now be used in executeAsync with a default-constructed (empty) MessageHandler.
