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_dependent_component, wsreg_remove_dependent_component, wsreg_get_dependent_components - add or remove a dependent component SYNOPSIS
cc [flag ...] file ...-lwsreg [library ...] #include <wsreg.h> int wsreg_add_dependent_component(Wsreg_component *comp, const Wsreg_component *dependentComp); int wsreg_remove_dependent_component(Wsreg_component *comp, const Wsreg_component *dependentComp); Wsreg_component **wsreg_get_dependent_components(const Wsreg_component *comp); DESCRIPTION
The wsreg_add_dependent_component() function adds the component specified by dependentComp to the list of dependent components contained in the component specified by comp. The wsreg_remove_dependent_component() function removes the component specified by dependentComp from the list of dependent components con- tained in the component specified by comp. The wsreg_get_dependent_components() function returns the list of dependent components contained in the component specified by comp. RETURN VALUES
The wsreg_add_dependent_component() function returns a non-zero value if the specified dependent component was successfully added; other- wise, 0 is returned. The wsreg_remove_dependent_component() function returns a non-zero value if the specified dependent component was successfully removed; otherwise, 0 is returned. The wsreg_get_dependent_components() function returns a null-terminated array of Wsreg_component pointers that represents the specified component's list of dependent components. If the specified component has no dependent 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 to use these functions because these relationships are held with lightweight compo- nent references that can only be fully resolved using the registry contents. The act of registering a component having required components results in the converse dependent relationships being established automati- cally. ATTRIBUTES
