BDA_PIN_PAIRING structure (bdasup.h)
The BDA_PIN_PAIRING structure describes the topology between a pair of input and output pins.
Syntax
typedef struct _BDA_PIN_PAIRING {
ULONG ulInputPin;
ULONG ulOutputPin;
ULONG ulcMaxInputsPerOutput;
ULONG ulcMinInputsPerOutput;
ULONG ulcMaxOutputsPerInput;
ULONG ulcMinOutputsPerInput;
ULONG ulcTopologyJoints;
const ULONG *pTopologyJoints;
} BDA_PIN_PAIRING, *PBDA_PIN_PAIRING;
Members
ulInputPin
Index of the element in the zero-based array of pin types (KSPIN_DESCRIPTOR_EX array) that indicates the input pin of the pair.
ulOutputPin
Index of the element in the zero-based array of pin types (KSPIN_DESCRIPTOR_EX array) that indicates the output pin of the pair.
ulcMaxInputsPerOutput
Maximum number of input pins per output pin. The network provider creates duplicates of nodes that are controlled by the input pin depending on the value specified in ulcMaxInputsPerOutput.
ulcMinInputsPerOutput
Minimum number of input pins per output pin. The network provider creates duplicates of nodes that are controlled by the input pin depending on the value specified in ulcMinInputsPerOutput.
ulcMaxOutputsPerInput
Maximum number of output pins per input pin. The network provider creates duplicates of nodes that are controlled by the output pin depending on the value specified in ulcMaxOutputsPerInput.
ulcMinOutputsPerInput
Minimum number of output pins per input pin. The network provider creates duplicates of nodes that are controlled by the output pin depending on the value specified in ulcMinOutputsPerInput.
ulcTopologyJoints
Number of joints in the pTopologyJoints array.
pTopologyJoints
Array of joint values. The value given to a joint corresponds to the index of an element in an array of template connections (KSTOPOLOGY_CONNECTION or BDA_TEMPLATE_CONNECTION array). A topology joint marks the point in the template topology where control of nodes switches from the input pin to the output pin. Those nodes that occur upstream of the topology joint are controlled through the input pin. Those nodes that occur downstream of the topology joint are controlled through the output pin.
