Deleting Symbolic links

NTFSD
1

Dear All,

I am working on a FileDisk program.
It creates a disk and assigns it a drive letter . Now i want to remove
drive letter from it. ie I

want to delete the symbolic link so as to delete the drive letter . For
this I am using following

code:

DEVICE_NAME_DEFINE \Device\Harddisk0\Partition1

UNICODE_STRING linkString;
RtlInitUnicodeString( &linkString, DEVICE_NAME_DEFINE);
IoDeleteSymbolicLink( &linkString );

The code is not throwing error and at same time is not working. Is there
any modifcation to be

done in above code ??
Alternatively please suggest any other method to achieve the same.

Thanks in advance.

Rohit

You must provide symbolic link name not symlink target name for
IoDeleteSymbolicLink. I.e. for your occasion the must look like this:

UNICODE_STRING SymbolicLinkName = RTL_CONSTANT_STRING(L"I:");
IoDeleteSymbolicLink(&SymbolicLinkName);

There is another way to do the same, try it.

DefineDosDevice(DDD_REMOVE_DEFINITION, Drive_Letter, NULL);
