IoCreateSymbolicLink in driver and DefineDosDevice in user mode is the same function?

NTFSD
1
  1. I use DefineDosDevice() to define a device to a volume, it is successful.
    For example : DefineDosDevice(DDD_RAW_TARGET_PATH, DrvLetter,DevicePath);
  2. But I use IoCreateSymbolicLink to define the same device to a volume, the
    routine returns value is success, but the volume is invisible.
    Fox example : IoCreateSymbolicLink(&symboliclink_name, &device_name);

And I use the winobj tool to check the symboliclink name, the second method
also can see the volume(for example “G:”) in the session.

Who can help me? thanks

*Where* do you create the symbolic link?

Also, are the permissions set correctly? To see whether this is the case, try using IoCreateUnprotectedSymbolicLink() instead of IoCreateSymbolicLink(). However, you should set the ACL to “sit tight”. It’s just a test.
