18 dbh_open () opens an existing DBHashTable at path in read/write mode
19 while dbh_openR () will open in read-only mode. To create, initialize
20 and open a new DBHashTable in read/write mode, dbh_create () is used.
21 key_length is the fixed length of the record access key and must be
22 less than 256. This only need be specified when the DBHashTable is cre‐
23 ated and initialized.

32 This function will overwrite any file with the specified path includ‐
33 ing any previous DBH file. Cuantified keys assure that large DBHashes
