Thread: error with function

Hi,

I am trying to write a function but keep getting an error when I try to build. I'm not very experienced with c++ so I can't really figure out what the error means. The funcion is called like this:

Code:

nMarkerCount = netClient.GetMarkerCount();

and it looks like this:

Code:

int BMLClient::GetMarkerCount(void)
{
	if (!m_bConnected) return 0; //??

	long cmd = 3;
	if (!Send(&cmd, sizeof(cmd)))
	{
		std::cout << "Unable to send <get marker data> command" << std::endl;
		return false;
	}
	long count;
	if (!Recv(&count,sizeof(count)))
	{
		std::cout << "Unable to get marker count" << std::endl;
		return false;
	}
	m_nMarkerCount = count;
	m_buffer = new double[count*3];
	m_bConnected = true;
	return m_nMarkerCount;
}

I have declared it as public in the header file like this:

Code:

int GetMarkerCount(void);

The error that I get says: error C2662: 'BMLClient::GetMarkerCount' : cannot convert 'this' pointer from 'const BMLClient' to 'BMLClient &'


Can anyone tell from what I've posted what this error means? Thanks!
