Routine Description:
|
|
|
|
This routine thunks the FILE_RENAME_INFORMATION structure IN PLACE. This means that the
|
|
original buffer will no longer be intact after this call! (However, it requires no memory
|
|
allocation either)
|
|
|
|
Arguments:
|
|
|
|
RxContext - the RDBSS context
|
|
|
|
Return Value:
|
|
|
|
RXSTATUS - The return status for the operation
|
|
|
|
Notes:
|
|
|
|
Remoting of FSCTL's is permitted only to NT servers.
