[other-attributes, hidden] function-type function-name(optional-parameter-list);

Parameters

other-attributes

Zero or more optional MIDL attributes.

element

One of the following directives: coclass, dispinterface, interface, or library.

element-name

The name that other software components can use to delineate the current element.

definitions

Specifies statements that make up the element definition.

function-type

Return type of the function.

function-name

Name used for invoking the function.

optional-parameter-list

Zero or more function parameters.

Remarks

The [hidden] attribute allows you to remove members from your interface (by shielding them from further use) while maintaining compatibility with existing code. You can use the [hidden] attribute on properties, methods, and the coclass, dispinterface, interface, and library statements.

When specified for a library, the [hidden] attribute prevents the entire library from being displayed. This usage is intended for use with controls. Hosts need to create a new type library that wraps the control with extended properties.

Flags

VARFLAG_FHIDDEN, FUNCFLAG_FHIDDEN, TYPEFLAG_FHIDDEN
