2.2.8.1.2.2 Fast-Path Input Event (TS_FP_INPUT_EVENT)

The TS_FP_INPUT_EVENT structure is used to describe the type and encapsulate the data for a fast-path input event sent from client to server. All fast-path input events conform to this basic structure (sections 2.2.8.1.2.2.1 to 2.2.8.1.2.2.6).

0	1	2	3	4	5	6	7	8	9	1 0	1	2	3	4	5	6	7	8	9	2 0	1	2	3	4	5	6	7	8	9	3 0	1
eventHeader								eventData (variable)
...

eventHeader (1 byte): An 8-bit, unsigned integer. One byte bit-packed event header. Two pieces of information are collapsed into this byte:

• Fast-path input event type

• Flags specific to the input event

The format of the eventHeader field is described by the following bitmask diagram.

0	1	2	3	4	5	6	7	8	9	1 0	1	2	3	4	5	6	7	8	9	2 0	1	2	3	4	5	6	7	8	9	3 0	1
eventFlags					eventCode

eventFlags (5 bits): A 5-bit unsigned integer that contains flags specific to the input event.

eventCode (3 bits): A 3-bit unsigned integer that specifies the type code of the input event.

Value (3 bits)	Meaning
FASTPATH_INPUT_EVENT_SCANCODE 0x0	Indicates a Fast-Path Keyboard Event (section 2.2.8.1.2.2.1).
FASTPATH_INPUT_EVENT_MOUSE 0x1	Indicates a Fast-Path Mouse Event (section 2.2.8.1.2.2.3).
FASTPATH_INPUT_EVENT_MOUSEX 0x2	Indicates a Fast-Path Extended Mouse Event (section 2.2.8.1.2.2.4).
FASTPATH_INPUT_EVENT_SYNC 0x3	Indicates a Fast-Path Synchronize Event (section 2.2.8.1.2.2.5).
FASTPATH_INPUT_EVENT_UNICODE 0x4	Indicates a Fast-Path Unicode Keyboard Event (section 2.2.8.1.2.2.2).
FASTPATH_INPUT_EVENT_MOUSEREL 0x5	Indicates a Fast Path Relative Mouse Event (section 2.2.8.1.2.2.7).
FASTPATH_INPUT_EVENT_QOE_TIMESTAMP 0x6	Indicates a Fast-Path Quality of Experience (QoE) Timestamp Event (section 2.2.8.1.2.2.6).

eventData (variable): Optional and variable-length data specific to the input event.
