EVT_ACX_PIN_CONNECTED callback function (acxpin.h)

  • Article

The EVT_ACX_PIN_CONNECTED callback function is implemented by the driver and is called when the circuit bridge pin is connected to bridge pin of another circuit.

Syntax

EVT_ACX_PIN_CONNECTED EvtAcxPinConnected;

void EvtAcxPinConnected(
  ACXPIN Pin,
  ACXTARGETCIRCUIT TargetCircuit,
  ULONG TargetPinId
)
{...}

Parameters

Pin

An ACXPIN object representing the specific pin that was connected.

TargetCircuit

An ACXTARGETCIRCUIT object representing the circuit to which the Pin was connected.

TargetPinId

The identifier of the pin in the TargetCircuit to which the Pin was connected.

Return value

None

Remarks

This event happens when the composite circuit is fully initialized. From this point on, the TargetCircuit can be used to send kernel streaming properties and kernel streaming methods requests.

ACX requirements

Minimum ACX version: 1.0
