WDM驱动AddDevice例程中指定设备名的问题

普通WINDOWS的驱动目前不太火呵呵。

两段ddk里的关于IOCreateDeive()中关于device name 参数原文，以及microsoft 关于如何name a device driver, 相信看了你就释然了。
驱动开发还是很有qian途的。加油。

1. “DeviceName （）
Optionally points to a buffer containing a zero-terminated Unicode string that names the device object. The string must be a full path name.
Typically, only physical device objects (PDOs), which are created by PnP bus drivers, are named. PnP function drivers and filter drivers should not specify a DeviceName for a functional device object (FDO) or filter device object (filter DO). Naming an FDO or filter DO bypasses the PnP Manager's security. If a user-mode component needs a symbolic link to the device, the function or filter driver should register a device interface (see IoRegisterDeviceInterface ). If a kernel-mode component needs a legacy device name, the driver must name the FDO, but naming is not recommended. "

2."
IoCreateDevice can only be used to create an unnamed device object, or a named device object for which a security descriptor is set by an INF file. Otherwise, drivers must use IoCreateDeviceSecure to create named device objects.

你好像没有导出符号连接名啊：

UNICODE_STRING? ? ? ? deviceNameUnicodeString;
RtlInitUnicodeString(&deviceNameUnicodeString, NT_DEVICE_NAME);

NTSTATUS status = STATUS_SUCCESS;

status = IoCreateDevice(DriverObject, sizeof(DEVICE_EXTENSION),
&deviceNameUnicodeString,FILE_DEVICE_UNKNOWN,
0, false, &FunctionDevice);

if (!NT_SUCCESS(status))
{
DT("%s IoCreateDevice VMouse failed", FUN);
return status;
}

UNICODE_STRING deviceLinkUnicodeString;
RtlInitUnicodeString(&deviceLinkUnicodeString, DOS_DEVICE_NAME);
status = IoCreateSymbolicLink(&deviceLinkUnicodeString, &deviceNameUnicodeString);
if (!NT_SUCCESS(status))
{
DT("%s IoCreateSymbolicLink VMouse failed", FUN);
if (FunctionDevice)
{
IoDeleteDevice(FunctionDevice);
return status;
}
}
