View the official Windows hardware development documentationNo description available.
The GetIpInterfaceTable function retrieves the IP interface entries on a local computer.
Family [in] The address family of IP interfaces to retrieve.
Possible values for the address family are listed in the Winsock2.h header file. Note that the values for the AF_ address family and PF_ protocol family constants are identical (for example, AF_INET and PF_INET), so you can use either constant.
On Windows Vista and later versions of the Windows operating systems, possible values for the Family parameter are defined in the Ws2def.h header file. Note that the Ws2def.h header file is automatically included in Netioapi.h and you should never use Ws2def.h directly.
The following values are currently supported for the address family:
AF_INET The IPv4 address family.
AF_INET6 The IPv6 address family.
AF_UNSPEC The address family is unspecified. When this value is specified, the GetIpInterfaceTable function returns the IP interface table that contains both IPv4 and IPv6 entries.
Table [out] A pointer to a buffer that receives the table of IP interface entries in a MIB_IPINTERFACE_TABLE structure.
GetIpInterfaceTable returns STATUS_SUCCESS if the function succeeds.
If the function fails, GetIpInterfaceTable returns one of the following error codes:
| Return code | Description |
|---|---|
| STATUS_INVALID_PARAMETER | An invalid parameter was passed to the function. This error is returned if a NULL pointer is passed in the Table parameter or the Family parameter was not specified as AF_INET, AF_INET6, or AF_UNSPEC. |
| STATUS_NOT_ENOUGH_MEMORY | Insufficient memory resources are available to complete the operation. |
| STATUS_NOT_FOUND | No IP interface entries, as specified in the Family parameter, were found. |
| STATUS_NOT_SUPPORTED | The function is not supported. This error is returned when the IP transport that is specified in the Address parameter is not configured on the local computer. This error is also returned on versions of Windows where this function is not supported. |
| Other | Use the FormatMessage function to obtain the message string for the returned error. |
The GetIpInterfaceTable function enumerates the IP interfaces on a local computer and returns this information in an MIB_IPINTERFACE_TABLE structure.
GetIpInterfaceTable returns IP interface entries in a MIB_IPINTERFACE_TABLE structure in the buffer that the Table parameter points to. The MIB_IPINTERFACE_TABLE structure contains an IP interface entry count and an array of MIB_IPINTERFACE_ROW structures for each IP interface entry. When these returned structures are no longer required, your driver should free the memory by calling the FreeMibTable function.
Your driver must initialize the Family parameter to either AF_INET or AF_INET6.
Note that the returned MIB_IPINTERFACE_TABLE structure that the Table parameter points to might contain padding for alignment between the NumEntries member and the first MIB_IPINTERFACE_ROW array entry in the Table member of the MIB_IPINTERFACE_TABLE structure. Padding for alignment might also be present between the MIB_IPINTERFACE_ROW array entries. Any access to a MIB_IPINTERFACE_ROW array entry should assume padding might exist.
