- set or get the instance of a query
cc [flag …] file …-lwsreg [library …] #include <wsreg.h> int wsreg_query_set_instance(Wsreg_query *query, int instance);
int wsreg_query_get_instance(Wsreg_query *comp);
The wsreg_query_set_instance() function sets the instance number specified by instance in the query specified by query.
The wsreg_query_get_instance() function retrieves the instance from the query specified by query.
The wsreg_query_set_instance() function returns a non-zero value if the instance was set correctly; otherwise 0 is returned.
The wsreg_query_get_instance() function returns the instance number from the specified query. It returns 0 if the instance number has not been set.
The query identifies fields used to search for a specific component in the product install registry. By specifying the instance, the component search is narrowed to all components in the product install registry that have the specified instance.
Other fields can be specified in the same query to further narrow down the search.
