Is there a feature equivalent to Indy9's TIdTCPConnection.ReadBuffer?

Indy9 Code

 void__fastcall TfrmMain::ServerConnect (TIdPeerThread*AThread)
{
     BKUK_PACKET Pkt;
-----------------------------------------------------------

AThread->Connection->ReadBuffer(BYTE*)&Pkt,sizeof(BKUK_PACKET));

-----------------------------------------------------------
}

I can't find a feature called ReadBuffer in Indy10, but is there a similar feature?

The code seems to be moving the received BKUK_PACKET data to the memory location of the Pkt pointer.

BKUK_PACKET is about 1200 bytes of data like this.

typedef structure_BKUK_PACKET_
{
    BYTE head [4];
    WORD PayLoad;
    WORD Length;
    BYTE Data [1200];
    WORD VER;
    BYTE tail [2];
}BKUK_PACKET;

When I used Indy before, I received data, etc.

AnsiString rcvdStr;


    rcvdStr = AContext->Connection->IOHandler->ReadLn (IndyTextEncoding (932));

I have received data like this before, but can I still use ReadLn() in this case?

(Movement)

Context->Connection->IOHandler->ReadBytes(BYTE*)&Pkt,sizeof(BKUK_PACKET))

I found a feature called ReadBytes and tried to program it as above, but I got the following error:

[bcc32c Error] Main.cpp(530): non-const value reference to type 'Idglobal::TIdBytes' (aka 'DynamicArray') cannot bind to a temporary of type 'BYTE*' (aka 'unsigned char*')
IdIOHandler.hpp(235): passing argument to parameter 'VBuffer'here

I get this kind of error, is there any way to deal with it?
