The Peer Graphing API uses the following functions:
Initialization and Cleanup Functions
| Function | Description |
|---|---|
| PeerGraphShutdown | Cleans up any resources allocated by the call to PeerGraphStartup. |
| PeerGraphStartup | Indicates to the Peer Graphing Infrastructure what version of the Peer protocols the calling application requires. |
Graph Creation and Access Functions
| Function | Description |
|---|---|
| PeerGraphClose | Invalidates the peer graph handle returned by a call to either PeerGraphCreate or PeerGraphOpen, and closes all network connections for the specified peer graph. |
| PeerGraphCreate | Creates a new peer graph. |
| PeerGraphDelete | Deletes the data associated with a specified peer graph. |
| PeerGraphListen | Indicates that a peer graph should start listening for incoming connections. |
| PeerGraphOpen | Opens a peer graph that is created previously by either the local node or a remote node. |
Graph and Node Information Functions
| Function | Description |
|---|---|
| PeerGraphEnumNodes | Creates and returns an enumeration handle used to enumerate the nodes in a peer graph. |
| PeerGraphGetNodeInfo | Retrieves information about a specific node. |
| PeerGraphGetProperties | Retrieves the current peer graph properties. |
| PeerGraphGetStatus | Returns the current status of the peer graph. |
| PeerGraphSetNodeAttributes | Sets the attributes of the PEER_NODE_INFO structure for the local node. |
| PeerGraphSetPresence | Explicitly turns on or off the publication of presence records for a specific node. This function can override the presence settings in the peer graph properties. |
| PeerGraphSetProperties | Sets the peer graph properties. |
Record Management Functions
| Function | Description |
|---|---|
| PeerGraphAddRecord | Adds a new record to a peer graph. A record added with this function is sent to each node in a peer graph. |
| PeerGraphDeleteRecord | Marks a record as deleted within a peer graph. |
| PeerGraphEnumRecords | Creates and returns an enumeration handle used to enumerate records of a specific type of record, user, or both. |
| PeerGraphGetRecord | Retrieves a specific record based on the specified record ID. |
| PeerGraphSearchRecords | Searches the peer graph for specific records. |
| PeerGraphUpdateRecord | Updates a record in the peer graph and then floods the record to each node in the peer graph. |
| PeerGraphValidateDeferredRecords | Indicates to the Peer Graphing Infrastructure that it is time to resubmit any deferred records for the security module to validate. |
Export and Import Functions
| Function | Description |
|---|---|
| PeerGraphExportDatabase | Exports a peer graph database into a file that you can move to a different computer. |
| PeerGraphImportDatabase | Imports a file that contains the information from a peer graph database. |
Utility and Support Functions
| Function | Description |
|---|---|
| PeerGraphEndEnumeration | Releases an enumeration handle, and frees the resources associated with an enumeration. |
| PeerGraphFreeData | Frees resources that several of the Peer Graphing API functions return. |
| PeerGraphGetItemCount | Retrieves the number of items in an enumeration. |
| PeerGraphGetNextItem | Obtains the next item or items in an enumeration created by a call to specific functions, which return a peer enumeration. |
| PeerGraphPeerTimeToUniversalTime | Converts the peer graph-maintained reference time value to a localized time value appropriate for display on the peer's computer. |
| PeerGraphUniversalTimeToPeerTime | Converts a universal time value from the peer's computer to a common peer graph time value. |
Connection Functions
| Function | Description |
|---|---|
| PeerGraphCloseDirectConnection | Closes a specified direct connection. |
| PeerGraphConnect | Attempts to make a connection to a specified node in a peer graph. This function starts an asynchronous operation. |
| PeerGraphEnumConnections | Creates and returns an enumeration handle used to enumerate the connections of a local node. |
| PeerGraphOpenDirectConnection | Allows an application to establish a direct connection with a node in a peer graph. The connection can only be made if the node to which the application is connecting has subscribed to the PEER_GRAPH_EVENT_DIRECT_CONNECTION event. |
| PeerGraphSendData | Sends data to a neighbor node or a directly connected node. |
Events Infrastructure Functions
| Function | Description |
|---|---|
| PeerGraphGetEventData | Retrieves peer events. |
| PeerGraphRegisterEvent | Registers a peer's request to be notified of changes associated with a peer graph and event type. |
| PeerGraphUnregisterEvent | Requests that the application no longer be notified of changes associated with a peer graph and record type. |
