<p>
Replace Berkeley DB calls to the ANSI C X3.159-1989 (ANSI C) standard
<span class="bold"><strong>realloc</strong></span> function with <span class="bold"><strong>func_realloc</strong></span>, which must conform to the
standard interface specification.
</p>
<p>
The <code class="function">db_env_set_func_realloc()</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_realloc()</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_realloc()</code> <span>
function returns a non-zero error value on failure and 0 on success.
</span>
