The Berkeley DB library requires the ability to return any memory
allocated as part of the routine which reads through a directory and
creates a list of files that the directory contains (see
<a class="xref" href="db_env_set_func_dirlist.html" title="db_env_set_func_dirlist">db_env_set_func_dirlist</a>).
</p>
<p>
The <code class="function">db_env_set_func_dirfree()</code> function configures all operations performed
by a process and all of its threads of control, not operations
confined to a single database environment.
</p>
<p>
Although the <code class="function">db_env_set_func_dirfree()</code> function may be called at any time
during the life of the application, it should normally be called
before making calls to the <a class="xref" href="envcreate.html" title="db_env_create">db_env_create</a> or
<a class="xref" href="dbcreate.html" title="db_create">db_create</a> methods.
</p>
<p>
The <code class="function">db_env_set_func_dirfree()</code> <span>
function returns a non-zero error value on failure and 0 on success.

The <span class="bold"><strong>func_dirfree</strong></span> parameter is a
function which frees the memory returned from the
