Parameters
_LOCAL_DEVICE_INFO*
Type for a pointer to a LOCAL_DEVICE_INFO structure.
PIRP
Type for a pointer to an IRP structure.
PIO_STACK_LOCATION
Type for a pointer to an IO_STACK_LOCATION structure.
Return Value
Returns STATUS_SUCCESS if the operation succeeds. Otherwise returns an NTSTATUS error code.
