int wsreg_query_set_id(Wsreg_query *query, const char *uuid);

char *wsreg_query_get_id(const Wsreg_query *query);

Description

The wsreg_query_set_id() function sets the uuid (universal unique identifier) specified by uuid in the query specified by query. If a uuid has already been set in the specified query, the resources associated with the previously set uuid are released.

The wsreg_query_get_id() function returns the uuid associated with the query specified by query. The resulting string is not a copy and must not be released by the caller.

Return Values

The wsreg_query_set_id() function returns non-zero if the uuid was set correctly; otherwise 0 is returned.

The wsreg_query_get_id() function returns the uuid associated with the specified query.

Usage

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

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