TCP Write Raw data

[^NyAw^]

Hi,

I'm trying to write raw data thorugh TCPSocket. I have a struct like (Modbus protocol):

//Modbus header
	typedef struct MB_Request
	{
		uchar function_code;
		quint16 start_adr;
		quint16 quantity_regs;
	};
 
	//Modbus/TCP header, containing the Modbus header
	typedef struct MBAP_Header
	{
		quint16 transaction_id;
		quint16 protocol_id;
		quint16 len;
		uchar unit_id;
	};
 
	typedef struct MB_Message
	{
		MBAP_Header mb_hdr;
		MB_Request mb_req;
	};

//Modbus header
	typedef struct MB_Request
	{
		uchar function_code;
		quint16 start_adr;
		quint16 quantity_regs;
	};

	//Modbus/TCP header, containing the Modbus header
	typedef struct MBAP_Header
	{
		quint16 transaction_id;
		quint16 protocol_id;
		quint16 len;
		uchar unit_id;
	};

	typedef struct MB_Message
	{
		MBAP_Header mb_hdr;
		MB_Request mb_req;
	};

To copy to clipboard, switch view to plain text mode 

What I don't know is how to send a variable (MB_Message type) as raw data. The documentation show that the data have to be stored as "char *". How have I to do this?

Thanks,
