TSoInetIfQuery Class Reference

class TSoInetIfQuery

Interface query.

Used with interface query options:

Only GetOption for KSolInetIfQuery is supported. It returns information about the selected interface. The option name determines the input field in the TSoInetIfQuery , which is used as a key for locating the interface.

Returns, KErrNotFound, if interface is not found

Returns, KErrNone, if interface is located, and fills fields from the interface with following logic

iDstAddr: not touched, left as is
iSrcAddr is result of the Select Source Address algorithm for the interface using the iDstAddr as input. If there is no valid source address, the value will be KAFUnspec.
iIndex is loaded with the interface index of the interface
iName is loaded from the name of the interface
iIsUp is set 1, if interface has CNifIfBase pointer attached, and 0 otherwise.

For example, if QueryByDstAddr for specified destination address results iIsUp == 1, then there is an interface and route for that destination. iIsUp == 0, means that trying to connect to the address will most likely activate a netdial/interface link startup phase.

TInetAddr iDstAddr

TInetAddr

iDstAddr

Destination address.

input: If the option is KSoInetIfQueryByDstAddr , select interface by finding a route for this address; otherwise, ignored.
output: not changed.

Note:

On returning interface information, regardless of the option used, the content of this is used to select a matching source address ( iSrcAddr ).

TUint32 iIndex

TUint32

iIndex

Interface Index.

input: If the option is KSoInetIfQueryByIndex , select interface by this interface index; otherwise, ignored.
output: The interface index the located interface. (always same as iZone[0] in 7.0s).

TUint iIsUp

TUint

iIsUp

Flag that is set to 1 if the network interface is attached.

input: ignored
output: set as indicated.

TName iName

TName

iName

Interface name.

input: If the option is KSoInetIfQueryByName , select interface by this name; otherwise, ignored.
output: The name of the located interface.

TInetAddr iSrcAddr

TInetAddr

iSrcAddr

Source address.

input: If the option is KSoInetIfQueryBySrcAddr , select interface by source address; otherwise, ignored.
output: The result of the source address selection algorithm based on the content of the iDstAddr .

TInetScopeIds iZone

TInetScopeIds

iZone

Scope Id Vector (iZone[0] = Interface Index, iZone[1] = IAP ID, iZone[15] = Network ID).

input: ignored
output: The scope id vector
