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.
