<h1><a name="description">DESCRIPTION</a></h1>
<p>In the description here, <em>TYPE</em> is used a placeholder
for any of the OpenSSL datatypes listed in
<em>CRYPTO_get_ex_new_index(3)</em>.</p>
<p>These functions handle application-specific data for OpenSSL data
structures.</p>
<p><code>TYPE_get_ex_new_index()</code> is a macro that calls <code>CRYPTO_get_ex_new_index()</code>
with the correct <strong>index</strong> value.</p>
<p><code>TYPE_set_ex_data()</code> is a function that calls <code>CRYPTO_set_ex_data()</code> with
an offset into the opaque exdata part of the TYPE object.</p>
<p><code>TYPE_get_ex_data()</code> is a function that calls <code>CRYPTO_get_ex_data()</code> with
an offset into the opaque exdata part of the TYPE object.</p>
<p>
</p>
<hr />
<h1><a name="return_values">RETURN VALUES</a></h1>
<p><code>TYPE_get_ex_new_index()</code> returns a new index on success or -1 on error.</p>
<p><code>TYPE_set_ex_data()</code> returns 1 on success or 0 on error.</p>
<p><code>TYPE_get_ex_data()</code> returns the application data or NULL if an error occurred.</p>
