ConstructL(TInt, TInt)

void	ConstructL	(	TInt	aToken,
			TInt	aKey
		)

Parameters

TInt aToken
TInt aKey

NewL(TInt, TInt)

IMPORT_C CAlfCompositionHost *	NewL	(	TInt	aToken,
			TInt	aKey
		)	[static]

Constructor for application that wishes modify composition information for some other process, see CreatePermissionToken()

Leaves using KErrNotFound, if token is not valid

If the binded target layer is destroyed by its owner, any Set operations will have no effect.

Parameters

TInt aToken
TInt aKey
