Component Manager Data Structures

"Data Structures for Applications" defines the data structures your application can use to interact with components.

The component description record ComponentDescription identifies the characteristics of a component, including the type of services offered by the component and its manufacturer. It is used by FindNextComponent , CountComponents , GetComponentInfo , and RegisterComponent . See "The Component Description Record" .
Component identifiers and component instances are two similar ways of specifying components. They are used by most Component Manager routines. See "Component Identifiers and Component Instances" .
The component parameters record ComponentParameters is used to pass parameters, along with information about the current connection, between an application and a component. It is used by the component and by CallComponentFunction , CallComponentFunctionWithStorage , and DelegateComponentCall . See "The Component Parameters Record" .
