BDA_TEMPLATE_CONNECTION structure (bdatypes.h)

  • Article

The BDA_TEMPLATE_CONNECTION structure describes the template for a BDA connection in terms of where it begins and ends.

Syntax

typedef struct _BDA_TEMPLATE_CONNECTION {
  ULONG FromNodeType;
  ULONG FromNodePinType;
  ULONG ToNodeType;
  ULONG ToNodePinType;
} BDA_TEMPLATE_CONNECTION, *PBDA_TEMPLATE_CONNECTION;

Members

FromNodeType

Index of the element in the zero-based array of internal node types (KSNODE_DESCRIPTOR array) that indicates the node type where the connection begins or −1 to indicate that the connection begins at an upstream filter.

FromNodePinType

Index of the element in the zero-based array of pin types (KSPIN_DESCRIPTOR_EX array) that indicates the pin type where the connection begins. The array of pin types is the list of pin types that are available in the filter's template topology.

ToNodeType

Index of the element in the zero-based array of internal node types (KSNODE_DESCRIPTOR array) that indicates the node type where the connection ends or −1 to indicate that the connection ends at a downstream filter.

ToNodePinType

Index of the element in the zero-based array of pin types (KSPIN_DESCRIPTOR_EX array) that indicates the pin type where the connection ends. The array of pin types is the list of pin types that are available in the filter's template topology.
