RtlCopyMemory()和READ_REGISTER_UCHAR()函数是在哪里定义的?

case IOCTL_PDC1000_READ_DATA:
unsigned char Num,Buffer;

PdcAddress = (ULONG)pdx->PdcMemBase;

RtlCopyMemory(&Num, pIrp->AssociatedIrp.SystemBuffer, 1);
DebugPrint(\"Input Value is %x.\",Num);
Buffer = READ_REGISTER_UCHAR((unsigned char *)(PdcAddress + Num));
DebugPrint(\"Read Data Value is %x.\",Buffer);
RtlCopyMemory( pIrp->AssociatedIrp.SystemBuffer,&Buffer,1);
ReturnedValue = 1;
break;

奥,刚在DDK里面查到了
