NAME
wsreg_add_child_component, wsreg_remove_child_component, wsreg_get_child_components - add or remove a child component SYNOPSIS
cc [flag ...] file ...-lwsreg [library ...] #include <wsreg.h> int wsreg_add_child_component(Wsreg_component *comp, const Wsreg_component *childComp); int wsreg_remove_child_component(Wsreg_component *comp, const Wsreg_component *childComp); Wsreg_component **wsreg_get_child_components(const Wsreg_component *comp); DESCRIPTION
The wsreg_add_child_component() function adds the component specified by childComp to the list of child components contained in the compo- nent 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. RETURN VALUES
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 compo- nent'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). USAGE
The parent-child relationship between components in the product install registry is used to record a product's structure. Product struc- ture 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 light- weight component references that can only be fully resolved using the registry contents.

NAME
wsreg_set_parent, wsreg_get_parent - set or get the parent of a component SYNOPSIS
cc [flag ...] file ...-lwsreg [library ...] #include <wsreg.h> void wsreg_set_parent(Wsreg_component *comp, const Wsreg_component *parent); Wsreg_component *wsreg_get_parent(const Wsreg_component *comp); DESCRIPTION
The wsreg_set_parent() function sets the parent specified by parent of the component specified by comp. The wsreg_get_parent() function gets the parent of the component specified by comp. RETURN VALUES
The wsreg_get_parent() function returns a pointer to a Wsreg_component structure that represents the parent of the specified component. If the specified component does not have a parent, NULL is returned. If a non-null value is returned, it the caller's responsibility to release the memory associated with the resulting Wsreg_component pointer with a call to wsreg_free_component(). See wsreg_create_compo- nent(3WSREG). USAGE
The parent of a component is set as a result of registering the parent component. When a component that has children is registered, all of the child components are updated to reflect the newly registered component as their parent. This update only occurs if the child component does not already have a parent component set. The specified parent component is reduced to a lightweight component reference that uniquely identifies the parent in the product install registry. This lightweight reference includes the parent's uuid and instance number. The parent must be registered before a call to wsreg_set_parent() can be made, since the parent's instance number must be known at the time the wsreg_set_parent() function is called. A process needing to call wsreg_set_parent() or wsreg_get_parent() must have read access to the product install registry. ATTRIBUTES
