## Deleting Records Using Cursors

To delete a record using a cursor, simply position the cursor to the record that you want to delete and then call `DBC->del()`.

For example:

    #include <db.h>
    #include <string.h>

    ...

    DB *dbp;
    DBC *cursorp;
    DBT key, data;
    char *key1str = "My first string";
    int ret;

    /* Database open omitted */

    /* Initialize our DBTs. */
    memset(&key, 0, sizeof(DBT));
    memset(&data, 0, sizeof(DBT));

    /* Set up our DBTs */
    key.data = key1str;
    key.size = strlen(key1str) + 1;

    /* Get the cursor */
    dbp->cursor(dbp, NULL, &cursorp, 0);

    /* Iterate over the database, deleting each record in turn. */
    while ((ret = cursorp->get(cursorp, &key,
                   &data, DB_SET)) == 0) {
        cursorp->del(cursorp, 0);
    }

    /* Cursors must be closed */
    if (cursorp != NULL)
        cursorp->close(cursorp);

    if (dbp != NULL)
        dbp->close(dbp, 0);
