PEER_NODE_INFO structure (p2p.h)

The PEER_NODE_INFO structure contains information that is specific to a particular node in a peer graph.

Syntax

typedef struct peer_node_info_tag {
  DWORD         dwSize;
  ULONGLONG     ullNodeId;
  PWSTR         pwzPeerId;
  ULONG         cAddresses;
  PPEER_ADDRESS pAddresses;
  PWSTR         pwzAttributes;
} PEER_NODE_INFO, *PPEER_NODE_INFO;

Members

dwSize

Specifies the size of the data structure. Set the value to sizeof(PEER_NODE_INFO). This member is required and has no default value.

ullNodeId

Specifies a unique ID that identifies an application's connection to its neighbor. An application cannot set the value of this member, it is created by the Peer Graphing Infrastructure.

pwzPeerId

Specifies the ID of this peer. This value is set for the application by the Peer Graphing Infrastructure. when the application creates or opens a peer graph.

cAddresses

Specifies the number of addresses in pAddresses. This member is required and has no default value.

pAddresses

Points to an array of PEER_ADDRESS structures that indicate which addresses and ports this instance is listening to for group traffic. This member is required and has no default value.

pwzAttributes

Points to a string that contains the attributes that describe this particular node. This string is a free-form text string that is specific to the application. This parameter is optional; the default value is NULL.
