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

The wsreg_query_get_location() function gets the location string from the query specified by query.

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

The wsreg_query_get_location() function returns the location from the specified query structure. The resulting location string is not a copy, so it must not be released by the caller.

The query identifies fields used to search for a specific component in the product install registry. By specifying the install location, the component search is narrowed to all components in the product install registry that are installed in the same location.

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