GetIfStackTable (Compact 7)
3/12/2014
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
If the function succeeds, the return value is NO_ERROR.
If the function fails, the return value is one of the following error codes.
| Return code | Description |
|---|---|
ERROR_INVALID_PARAMETER |
An invalid parameter was passed to the function. This error is returned if a NULL pointer is passed in the Table parameter. |
ERROR_NOT_ENOUGH_MEMORY |
Insufficient memory resources are available to complete the operation. |
ERROR_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 system and returns this information in a MIB_IFSTACK_TABLE structure.
Interface stack entries are returned in a MIB_IFSTACK_TABLE structure in the buffer pointed to by the Table parameter. 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, free the memory by calling the FreeMibTable.
Note that the returned MIB_IFSTACK_TABLE structure pointed to by the Table parameter may 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 may also be present between the MIB_IFSTACK_ROW array entries. Any access to a MIB_IFSTACK_ROW array entry should assume padding may exist.
