DESCRIPTION
The wsreg_query_set_instance() function sets the instance number speci‐
fied by instance in the query specified by query.
The wsreg_query_get_instance() function retrieves the instance from the
query specified by query.
RETURN VALUES
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.
USAGE
The query identifies fields used to search for a specific component in
the product install registry. By specifying the instance, the compo‐
nent search is narrowed to all components in the product install reg‐
istry that have the specified instance.
Other fields can be specified in the same query to further narrow down
the search.
