#include <apropos-utils.h>
query_args args;
char *errmsg = NULL;
int *sec_nums = {0, 1, 1, 0, 0, 0, 0, 0, 0};
args.search_str = argv[1];
args.sec_nums = sec_nums;
args.nrec = 10;
args.offset = -1;
args.machine = NULL;
args.callback = &query_callback;
args.callback_data = NULL;
args.errmsg = &errmsg;
if (run_query(db, &args) < 0)
errx(EXIT_FAILURE, "%s", errmsg);
}
free(query);
free(errmsg);
