CallFunctionAndCompleteL(TInt, TAny *, TInt, const RMessage2 &)

void	CallFunctionAndCompleteL	(	TInt	aFunc,
			TAny *	aParameter,
			TInt	aParLength,
			const RMessage2 &	aMessage
		)	[pure virtual]

Implements a raw function call. The implementation is supposed to interpret the parameters and satisfy the requests. The implemtation should also complete the message.

Parameters

TInt aFunc	Unique integer among the extended functions what function we are calling.
TAny * aParameter	A pointer to the parameter.
TInt aParLength	Length of the parameter.
const RMessage2 & aMessage	The message to be completed.

CallFunctionL(TInt, TAny *, TInt, TBool &)

TInt	CallFunctionL	(	TInt	aFunc,
			TAny *	aParameter,
			TInt	aParLength,
			TBool &	aParameterModified
		)	[pure virtual]

Implements a raw function call. The implementation is supposed to interpret the parameters and satisfy the requests.

Parameters

TInt aFunc	Unique integer among the extended functions what function we are calling.
TAny * aParameter	A pointer to the parameter.
TInt aParLength	Length of the parameter.
TBool & aParameterModified	ETrue if the content of aParameter has changed, EFalse otherwise
