<h3 align=center>Tcl API programming notes</h3>
<p>The Tcl API closely parallels the Berkeley DB programmatic interfaces. If you
are already familiar with one of those interfaces, there will not be many
surprises in the Tcl API.</p>
<p>The Tcl API currently does not support multithreading although
it could be made to do so. The Tcl shell itself is
not multithreaded and the Berkeley DB extensions use global data unprotected
from multiple threads.</p>
<p>Several pieces of Berkeley DB functionality are not available in the Tcl API.
Any of the functions that require a user-provided function are not
supported via the Tcl API. For example, there is no equivalent to the
<a href="../../api_c/db_set_dup_compare.html">DB->set_dup_compare</a> or the <a href="../../api_c/env_set_errcall.html">DB_ENV->set_errcall</a>
methods.</p>
