Attribute Conﬁguration Language

For a type—

typedef [heap] type_name;

For a parameter—

operation_name ([heap] parameter_name);

Any identiﬁer occurring as a parameter name within an operation declaration in the ACF

must also be a parameter name within the corresponding operation declaration in IDL.

The heap attribute is ignored for pipes, context handles, and scalars.

Example Using the heap Attribute

ACF

[auto_handle] interface galaxies

{

typedef [heap] big_array;

}

IDL File

[uuid(e61de280-0d0b-11ca-6145-08002b111685)]

interface galaxies

{

typedef long big_array[1000];

}

18.3.12 The extern_exceptions Attribute

By default, the IDL compiler declares and initializes all exceptions listed in an

exceptions interface attribute in the stub code that it generates. You can use the

extern_exceptions attribute to override this behavior; the extern_exceptions attribute

allows you to specify one or more exceptions listed in the exceptions interface attribute

that you do not want the IDL-generated stub code to declare. If the extern_exceptions

attribute appears with no list, it has the same effect as if all IDL-deﬁned exceptions were

speciﬁed in the list.

The extern_exceptions attribute has the following syntax. (See the example at the end

of this section.)

[extern_exceptions (exception_name [,exception_name]... )]

interface interface_name
