Hi,
But I need to get the drive letter before mounting the volume.
“ZwOpenSymbolicLinkObject” needs the object to be mounted before the
operation. Is there anyway for that…

name in kernel mode
Hello,
QueryDosDevice is a user mode WIN32 API function and
is not callable from kernel mode.
One needs to query the symbolic link objects ??\A:,
??\C:, ??\D: and so on using the Native APIs
ZwOpenSymbolicLinkObject and
ZwQuerySymbolicLinkObject.
