GetByAddress(TNameRecord &)

void

GetByAddress

(

TNameRecord &

aName

)

[pure virtual]

Gets the Host name by address

Parameters

TNameRecord & aName

GetByName(TNameRecord &)

void

GetByName

(

TNameRecord &

aName

)

[pure virtual]

Get the Host name by name

Parameters

TNameRecord & aName

GetHostName(TDes &)

void

GetHostName

(

TDes &

aNameBuf

)

[pure virtual]

Gets the Host name

Parameters

TDes & aNameBuf

Query(const TDesC8 &, TDes8 &, TInt)

IMPORT_C void	Query	(	const TDesC8 &	aQryBuf,
			TDes8 &	aResBuf,
			TInt	aCounter
		)	[virtual]

Make a query to the protocol.

Note:

for aCounter > 0 data in aQryBuf are not supposed to be used.

Parameters

const TDesC8 & aQryBuf	descriptor representing query data.
TDes8 & aResBuf	descriptor representing query response data.
TInt aCounter	query sequential number counter. From the client's point of view it will be 0 for "Query" call and increased by 1 for each "QueryGetNext" call.

IMPORT_C TInt	SetOption	(	TUint	level,
			TUint	name,
			const TDesC8 &	anOption
		)	[virtual]

Default Set Option for Host Resolver

Sets options for the protocol on behalf of socket server clients

Parameters

TUint level
TUint name
const TDesC8 & anOption
