驱动层服务层：

#include <ntddk.h>

#define	 DEVICE_NAME "\\Device\\MyReadDevice"
#define  SYM_LINK_NAME	"\\??\\MyRead"

NTSTATUS DriverUnload(PDRIVER_OBJECT driver)
{
   
   
	DbgPrint("unload me");
	return STATUS_SUCCESS;
}

NTSTATUS MyDriverRead(PDEVICE_OBJECT device,PIRP pirp)
{
   
   
	PIO_STACK_LOCATION stack = IoGetCurrentIrpStackLocation(pirp);
	ULONG	readLength = stack->Parameters.Read.Length;
	pirp->IoStatus.Status = STATUS_SUCCESS;
	pirp->IoStatus.Information = readLength;
	memset(pirp->AssociatedIrp.SystemBuffer, 0x90, readLength);
	IoCompleteRequest(pirp, IO_NO_INCREMENT);
	DbgPrint("ReadOver\n")
