2.2.2.7.2 Server Move/Size Start PDU (TS_RAIL_ORDER_LOCALMOVESIZE)

The Server Move/Size Start PDU packet is sent by the server when a window on the server is beginning a move or resize. The client uses this information to initiate a local move or resize of the corresponding local window.

Hdr (4 bytes): A TS_RAIL_PDU_HEADER header. The orderType field of the header MUST be set to TS_RAIL_ORDER_LOCALMOVESIZE (0x0009).

WindowId (4 bytes): An unsigned 32-bit integer. The ID of the window on the server that is being moved or resized.

IsMoveSizeStart (2 bytes): An unsigned 16-bit integer. Indicates that the move/size is beginning; MUST be set to a nonzero value.

MoveSizeType (2 bytes): An unsigned 16-bit integer. Indicates the type of the move/size. This value determines the meaning of the fields PosX and PosY.

Value	Meaning
RAIL_WMSZ_LEFT 0x0001	The left edge of the window is being sized.
RAIL_WMSZ_RIGHT 0x0002	The right edge of the window is being sized.
