Hi,

How to copy array of structure values to
Irp->AssociatedIrp.SystemBuffer of a device driver, so that it can be sent to the application?

Thanks,

RtlMoveMemory is the traditional way.

Just by RtlCopyMemory(). The structures must not contain any pointers.

Don’t forget to set Irp->IoStatus.Information to the filled size in bytes,
it will be *BytesReturned in DeviceIoControl.
