Syntax

DWORD MprAdminTransportGetInfo(
  [in]            MPR_SERVER_HANDLE hMprServer,
  [in]            DWORD             dwTransportId,
  [out, optional] LPBYTE            *ppGlobalInfo,
  [out, optional] LPDWORD           lpdwGlobalInfoSize,
  [out, optional] LPBYTE            *ppClientInterfaceInfo,
  [out, optional] LPDWORD           lpdwClientInterfaceInfoSize
);

Parameters

[in] hMprServer

Handle to the router from which information is being retrieved. This handle is obtained from a previous call to MprAdminServerConnect.

[in] dwTransportId

A DWORD value that describes the transport type to retrieve. Acceptable values for dwTransportId are listed in the following table.

Value	Transport (Protocol Family)
PID_ATALK	AppleTalk
PID_IP	Internet Protocol version 4
PID_IPX	Internet Packet Exchange
PID_NBF	NetBIOS Frames Protocol
PID_IPV6	Windows Server 2008 or later: Internet Protocol version 6

[out, optional] ppGlobalInfo

Pointer to a pointer variable. This variable points to an information header that receives global information for this transport. Use the Information Header Functions to manipulate information headers.

Free this memory by calling MprAdminBufferFree.

This parameter is optional. If the calling application specifies NULL for this parameter, the function does not retrieve the global information.

[out, optional] lpdwGlobalInfoSize

Pointer to a DWORD variable. This variable receives the size, in bytes, of the global information for the transport.

[out, optional] ppClientInterfaceInfo

Pointer to a pointer variable. This variable points to default client interface information for this transport. Free this memory by calling MprAdminBufferFree.

This parameter is optional. If the calling application specifies NULL for this parameter, the function does not retrieve the client interface information.

[out, optional] lpdwClientInterfaceInfoSize

Pointer to a DWORD variable. This variable receives the size, in bytes, of the client interface information.

Return value

If the function succeeds, the return value is NO_ERROR.

If the function fails, the return value is one of the following error codes.

Value	Meaning
ERROR_ACCESS_DENIED	The calling application does not have sufficient privileges.
ERROR_INVALID_PARAMETER	One of the following is true: The ppGlobalInfo parameter and the ppClientInterfaceInfo parameter are both NULL. The ppGlobalInfo parameter does not point to valid memory. The ppClientInterfaceInfo parameter does not point to valid memory.
ERROR_NOT_ENOUGH_MEMORY	Insufficient resources to complete the operation.
ERROR_UNKNOWN_PROTOCOL_ID	The dwTransportId value does not match any installed transport.

Remarks

The ppGlobalInfo and ppClientInterfaceInfo parameters cannot both be NULL.
