After checking for successful status, the count of matching package records is checked. If there is at least one match, the first matching record is retrieved and dumped. Note that there could be more than one match. Although this example doesn't dump more than the first matching record, it would be simple to access all matches by stepping through the matches.recs array.

Once we're done with the record, we free it, as well as the list of matching records:

rpmdbClose(db);



}

The last thing we do before exiting is close the database. Here's some sample output from the program (note the successful status and the number of matches printed before the dump):

# ./showdb2 rpm

Status is: 0

Number of matches: 1

Entry count: 37

Data count : 2920
