From the components-builder manual:

part of invoking commands in c++, try the following:

bool mySendMsg(std::string peerName, std::string cdeName, std::string argValue)
{
Command mycom = this->getPeer(peerName)->commands()->getCommand("cdeName");
//executing the command
if (mycom.ready() ){
bool res = mycom(argValue);

// next, use any of the following :
bool accepted = mycom.accepted(); // accepted by execution engine?
bool valid = mycom.valid(); // command was valid (well-formed)?
bool done = mycom.done(); // command was done?

//print results
if(!res)
log(Info) << "executeMsg not OK" << endlog();
else
log(Info) << "executeMsg OK" << endlog();
}
return true;
}
