the current command can be set along with data of aLength2.

/**

Appends data directly to wserv buffer for the current command. So this function 

should be used after adding the current command.

Typically this function is used in conjunction with  

MWsClientClass::Write(const TAny *aData1,TInt aLength1,TInt aLength2,TUint aOpcode)

Please see its description for more details.  

@param aData Data to be added to the buffer

@param aLength Length of the data to be added to buffer. Make sure that its length

		is less than availabe buffer.

@param aFinished EFalse, adds data to buffer and disables flushing(notfies that more data is pending to be added)

				 ETrue, adds data to buffer and enables flushing(Signals that this is the last bit of data to be added)

Notes:

1. The total length of all data added by using this API(by one or more calls) must be less then(See note 3)or 

same as aLength2 passed in earlier call to MWsClientClass::Write(const TAny *aData1,TInt aLength1,TInt aLength2,TUint aOpcode)

2. When data is added using this API, it pads out buffer to multiple of 4 bytes so that 

all strings added to the buffer will begin on a 4 byte boundary.

3. If data added is less then the length passed to above Write API it works, but wastes buffer spaces.
