wsreg_add_compatible_version(3WSREG) Product Install Registry Library Functions wsreg_add_compatible_version(3WSREG) NAME
wsreg_add_compatible_version, wsreg_remove_compatible_version, wsreg_get_compatible_versions - add or remove a backward-compatible version SYNOPSIS
cc [flag ...] file ...-lwsreg [library ...] #include <wsreg.h> int wsreg_add_compatible_version(Wsreg_component *comp, const char *version); int wsreg_remove_compatible_version(Wsreg_component *comp, const char *version); char **wsreg_get_compatible_versions(const Wsreg_component *comp); DESCRIPTION
The wsreg_add_compatible_version() function adds the version string specified by version to the list of backward-compatible versions con- tained in the component specified by comp. The wsreg_remove_compatible_version() function removes the version string specified by version from the list of backward-compatible ver- sions contained in the component specified by comp. The wsreg_get_compatible_versions() function returns the list of backward-compatible versions contained in the component specified by comp. RETURN VALUES
The wsreg_add_compatible_version() function returns a non-zero value if the specified backward-compatible version was successfully added; otherwise, 0 is returned. The wsreg_remove_compatible_version() function returns a non-zero value if the specified backward-compatible version was successfully removed; otherwise, 0 is returned. The wsreg_get_compatible_versions() function returns a null-terminated array of char pointers that represents the specified component's list of backward-compatible versions. If the specified component has no such versions, NULL is returned. The resulting array and its con- tents must be released by the caller. USAGE
The list of backward compatible versions is used to allow components that are used by multiple products to upgrade successfully without compromising any of its dependent products. The installer that installs such an update can check the list of backward-compatible versions and look at what versions are required by all of the dependent components to ensure that the upgrade will not result in a broken product.

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.
