  • 项目

3/26/2014

This function retrieves a table of network interface stack row entries that specify the relationship of the network interfaces on an interface stack.

Syntax

NETIOAPI_API
  GetIfStackTable(
    OUT PMIB_IFSTACK_TABLE*  Table
    );

Parameters

  • Table
    A pointer to a buffer that receives the table of interface stack row entries in a MIB_IFSTACK_TABLE structure.

Return Value

GetIfStackTable returns STATUS_SUCCESS if the function succeeds.

If the function fails, GetIfStackTable returns one of the following error codes:

Error Code

Meaning

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.

STATUS_NOT_ENOUGH_MEMORY

Insufficient memory resources are available to complete the operation.

STATUS_NOT_FOUND

No interface stack entries were found.

Other

Use the FormatMessage function to obtain the message string for the returned error.

Remarks

The GetIfStackTable function enumerates the physical and logical network interfaces on an interface stack on a local device and returns this information in a MIB_IFSTACK_TABLE structure.

Interface stack entries are returned in a MIB_IFSTACK_TABLE structure in the buffer that the Table parameter points to. The MIB_IFSTACK_TABLE structure contains an interface stack entry count and an array of MIB_IFSTACK_ROW structures for each interface stack entry.

The relationship between the interfaces in the interface stack is that the interface with index in the HigherLayerInterfaceIndex member of the MIB_IFSTACK_ROW structure is immediately above the interface with index in the LowerLayerInterfaceIndex member of the MIB_IFSTACK_ROW structure.

Memory is allocated by the GetIfStackTable function for the MIB_IFSTACK_TABLE structure and the MIB_IFSTACK_ROW entries in this structure. When these returned structures are no longer required, your driver should free the memory by calling the FreeMibTable (NETIOAPI).

Note that the returned MIB_IFSTACK_TABLE structure that the Table parameter points to might contain padding for alignment between the NumEntries member and the first MIB_IFSTACK_ROW array entry in the Table member of the MIB_IFSTACK_TABLE structure. Padding for alignment might also be present between the MIB_IFSTACK_ROW array entries. Any access to a MIB_IFSTACK_ROW array entry should assume padding may exist.
