The Berkeley DB version 2 library provides
|
||
backward-compatible interfaces for the historic UNIX <a href="../api_reference/C/dbm.html" class="olink">dbm</a>,
|
||
<a href="../api_reference/C/dbm.html" class="olink">ndbm</a> and <a href="../api_reference/C/hsearch.html" class="olink">hsearch</a> interfaces. It also provides a
|
||
backward-compatible interface for the historic Berkeley DB
|
||
1.85 release.
|
||
</p>
|
||
<p>
|
||
Berkeley DB version 2 does not provide database
|
||
compatibility for any of the previous interfaces, and existing
|
||
databases must be converted manually. To convert existing
|
||
databases from the Berkeley DB 1.85 format to the Berkeley DB
|
||
version 2 format, review the <a href="../api_reference/C/db_dump.html" class="olink">db_dump185</a> utility and the <a href="../api_reference/C/db_load.html" class="olink">db_load</a> utility
|
||
information. No utilities are provided to convert UNIX <a href="../api_reference/C/dbm.html" class="olink">dbm</a>,
|
||
<a href="../api_reference/C/dbm.html" class="olink">ndbm</a> or <a href="../api_reference/C/hsearch.html" class="olink">hsearch</a> databases.
