Hi, all

could anyone give me an information about IOCTL 0x140FD3 ?

As far as I know, this IOCTL is sent by the CSCDLL library
(Offline folders handler or something like that) and is handled
by the MrxSmbCscIoctlCopyChunk routine.

It is IOCTL for FILE_DEVICE_NETWORK_FILE_SYSTEM,
Access 0, Function 1012, Method METHOD_NEITHER.

IrpSp->Parameters.DeviceIoCtrl.Type3InputBuffer
contains an information structure with file handle
at the offset 0x0C.

Does anyone know the name of the IOCTL
(is it IOCTL_MRXSMB_COPY_CHUNK ?)
and definition of the data structure for it ?

I would only to correct a mistake - the structure
with the file handle is not stored in the Type3InputBuffer, but in the
Irp->UserBuffer, as defined for IOCTLS of
the type METHOD_NEITHER.
