int results_per_fetch,
hc_query_result_set_t **rsetp);
Description
This function retrieves OIDs and optionally name-value records matching a query. If the
selects list is NULL, only OIDs are retrieved. If selects is not NULL, name-value records are
also retrieved and should each be freed using
“hc_nvr_free” on page 66. In both cases the result
set should be freed using
“hc_qrs_free” on page 99.
Note – When a query is incorrect and elicits an error from the server, the error is often reported
after
“hc_qrs_free” on page 99and not from hc_query_ez. Your application should be
prepared to receive and report an error from either place.
