wsreg_add_required_component(3WSREG)		    Product Install Registry Library Functions		      wsreg_add_required_component(3WSREG)

NAME

       wsreg_add_required_component, wsreg_remove_required_component, wsreg_get_required_components - add or remove a required component

SYNOPSIS

       cc [flag ...]  file ...-lwsreg [library ...]
       #include <wsreg.h>

       int wsreg_add_required_component(Wsreg_component *comp, const Wsreg_component *requiredComp);

       int wsreg_remove_required_component(Wsreg_component *comp, const Wsreg_component *requiredComp);

       Wsreg_component **wsreg_get_required_components(const Wsreg_component *comp);

DESCRIPTION

       The  wsreg_add_required_component()  function  adds the component specified by requiredComp to the list of required components contained in
       the component specified by comp.

       The wsreg_remove_required_component() function removes the component specified by requiredComp from the list of	required  components  con-
       tained in the component specified by comp.

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

RETURN VALUES

       The wsreg_add_required_component() function returns a non-zero value if the specified required component was successfully added. Otherwise,
       0 is returned.

       The wsreg_remove_required_component() function returns a non-zero value if the specified required component was successfully removed.  Oth-
       erwise, 0 is returned.

       The wsreg_get_required_components() function returns a null-terminated array of Wsreg_component pointers that represents the specified com-
       ponent's list of required components.  If the specified component has no required 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  relationship  between two components in which one must be installed for the other to be complete is a dependent/required relationship.
       The component that is required by the other component is the required component.  The component that requires the other	is  the  dependent
       component.

       The  required  component must be installed and registered before the dependent component can be.  Uninstaller applications should check the
       registry before uninstalling and unregistering components so a successful uninstallation of one product will not result in another  product
       being compromised.

       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.

wsreg_add_child_component(3WSREG)		    Product Install Registry Library Functions			 wsreg_add_child_component(3WSREG)

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.
