The get_CrossbarPinInfo method retrieves information about a specified pin.
Syntax
HRESULT get_CrossbarPinInfo (
BOOL IsInputPin,
long PinIndex,
long *PinIndexRelated,
long *PhysicalType
);
Parameters
IsInputPin
[in] Specifies the direction of the pin. Use one of the following values.
| Value | Description |
| TRUE | Input pin |
| FALSE | Output pin |
PinIndex
[in] Specifies the index of the pin.
PinIndexRelated
[out] Pointer to a variable that receives the index of the related pin, or -1 if no pin is related to this pin. The related pin is a pin on the same filter, with the same direction; it typically represents the same physical jack or connector. For example, a video tuner and an audio tuner might be related pins. Typically, if two pins are related, you should route them together.
PhysicalType
[out] Pointer to a variable that receives a member of the PhysicalConnectorType enumeration, indicating the pin's physical type.
Return Values
Returns an HRESULT value. Possible values include the following.
| Return code | Description |
| S_FALSE | Unknown physical type. |
| S_OK | Success. |
| E_POINTER | NULL pointer argument. |
Remarks
Output pins and input pins are both indexed from zero. To determine the number of output and input pins, call the IAMCrossbar::get_PinCounts method.
