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.
