NdfCreateGroupingIncident function (ndfapi.h)

  • Article

The NdfCreateGroupingIncident function creates a session to diagnose peer-to-peer grouping functionality issues.

Syntax

HRESULT NdfCreateGroupingIncident(
  [in, optional] LPCWSTR             CloudName,
  [in, optional] LPCWSTR             GroupName,
  [in, optional] LPCWSTR             Identity,
  [in, optional] LPCWSTR             Invitation,
  [in, optional] SOCKET_ADDRESS_LIST *Addresses,
  [in, optional] LPCWSTR             appId,
  [out]          NDFHANDLE           *handle
);

Parameters

[in, optional] CloudName

Type: LPCWSTR

The name of the Peer Name Resolution Protocol (PNRP) cloud where the group is created. If NULL, the session will not attempt to diagnose issues related to PNRP.

[in, optional] GroupName

Type: LPCWSTR

The name of the group to be diagnosed. If NULL, the session will not attempt to diagnose issues related to group availability.

[in, optional] Identity

Type: LPCWSTR

The identity that a peer uses to access the group. If NULL, the session will not attempt to diagnose issues related to the group's ability to register in PNRP.

[in, optional] Invitation

Type: LPCWSTR

An XML invitation granted by another peer. An invitation is created when the inviting peer calls PeerGroupCreateInvitation or PeerGroupIssueCredentials. If this value is present, the invitation will be checked to ensure its format and expiration are valid.

[in, optional] Addresses

Type: SOCKET_ADDRESS_LIST*

Optional list of addresses of the peers to which the application is trying to connect. If this parameter is used, the helper class will diagnose connectivity to these addresses.

[in, optional] appId

Type: LPCWSTR

Application ID for the calling application.

[out] handle

Type: NDFHANDLE*

Handle to the Network Diagnostics Framework incident.

Return value

Type: HRESULT

Possible return values include, but are not limited to, the following.

Return code Description
S_OK
 The operation succeeded.
NDF_E_BAD_PARAM
 One or more parameters has not been provided correctly.

Remarks

The level of diagnosis performed depends on the parameters supplied.

  • If no parameters are specified, NDF will validate the grouping service status, the status of peer-to-peer services (PNRP and Identity Manager), and Windows clock synchronization.
  • If CloudName is specified, NDF will validate grouping functionality in that cloud.
  • If GroupName is specified, NDF will validate that the name can be resolved in PNRP (or invoke the PNRP helper class if the name cannot be resolved) and validate the firewall settings for grouping.
  • If Identity is specified, NDF will validate PNRP's ability to register the GroupName with this Identity. If this fails, the PNRP helper class will be invoked.
  • If Invitation is specified, the GroupName will be derived from the Invitation (if a GroupName was not also specified) and NDF will validate the invitation's format and status.
  • If Addresses is specified, NDF will validate whether Windows can connect to up to three of these addresses.
