The wsreg_add_child_component() function adds the component specified by childComp to the list of child components contained in the component specified by comp.

The wsreg_remove_child_component() function removes the component specified by childComp from the list of child components contained in the component specified by comp.

The wsreg_get_child_components() function returns the list of child components contained in the component specified by comp.

The wsreg_add_child_component() function returns a non-zero value if the specified child component was successfully added; otherwise, 0 is returned.

The wsreg_remove_child_component() function returns a non-zero value if the specified child component was successfully removed; otherwise, 0 is returned.

The wsreg_get_child_components() function returns a null-terminated array of Wsreg_component pointers that represents the specified component's list of child components. If the specified component has no child components, NULL is returned. The resulting array must be released by the caller through a call to wsreg_free_component_array(). See wsreg_create_component(3WSREG).

The parent-child relationship between components in the product install registry is used to record a product's structure. Product structure is the arrangement of features and components that make up a product. The structure of installed products can be displayed with the prodreg GUI.

The child component must be installed and registered before the parent component can be. The registration of a parent component that has child components results in each of the child components being updated to reflect their parent component.

Read access to the product install registry is required in order to use these functions because these relationships are held with lightweight component references that can only be fully resolved using the registry contents.
