How do I send a c++ class object via boost::interprocess::message_queue?
Can someone share sample code for an IPC implementation using boost::interprocess::message_queue with IPC data as a Class object?

How can i send c++ class object via boost::interprocess::message_queue?
//Class Defination
#define MQ_DATA IPCMsg
class IPCMsg
{
public:
IPCMsg() { data = NULL; }
int len;
void* data;
};
// Initialize message Queue
mSendMq = new message_queue(OPEN_OR_CREATE, "MQ", 1024, sizeof(MQ_DATA));
mReceiveMq = new message_queue(OPEN_ONLY, "MQ");
// Send Data to message Queue
MQ_DATA* inData = new IPCMsg();
mSendMq->send(inData, sizeof(*inData), 0);
// Receive Data from message Queue
MQ_DATA* outdata = NULL;
mReceiveMq->receive(&outdata, sizeof(*outdata), 1024, priority);

Does this compile?

Note, that even if this did compile you are passing a raw pointer (uninitialized) --inData->data-- from the address space of one process to the address space of another and expecting it to be valid.

@G.M , It was compiling successfully. I have shared you the partial code. I was initializing "inData->data" and sending it to Message Queue. But observed, results were not as expected. Could you please help me in this regard by sharing some sample code for better understanding
