dbm-nextkey

Arguments: ndbm &key if-exists external-format return

dbm-nextkey returns the next key from the database ndbm. dbm-firstkey should have already been called on ndbm. The keyword arguments are the same as dbm-firstkey.

Note: If you call dbm-store or dbm-delete while traversing a database using dbm-firstkey/dbm-nextkey, you should restart the traversal by calling dbm-firstkey again.

See ndbm.htm for information on the NDBM facility.
