The wsreg_query_set_unique_name() function sets the unique name specified by unique_name in the query specified by query. If a unique name has already been set in the specified query, the resources associated with the previously set unique name are released.

The wsreg_query_get_unique_name() function gets the unique name string from the query specified by query. The resulting string is not a copy and must not be released by the caller.

The wsreg_query_set_unique_name() function returns a non-zero value if the unique_name was set correctly; otherwise 0 is returned.

The wsreg_query_get_unique_name() function returns a copy of the unique_name from the specified query.

The query identifies fields used to search for a specific component in the product install registry. By specifying the unique name, the component search is narrowed to all components in the product install registry that have the specified unique name.

Other fields can be specified in the same query to further narrow the search.
