<p>The following functions have been deprecated since OpenSSL 3.0, and can be hidden entirely by defining <b>OPENSSL_API_COMPAT</b> with a suitable version value, see <a href="../man7/openssl_user_macros.html">openssl_user_macros(7)</a>:</p>

|
<p>DH_new() allocates and initializes a <b>DH</b> structure.</p>
|
||
|
|
|
||
|
|
<p>DH_free() frees the <b>DH</b> structure and its components. The values are erased before the memory is returned to the system. If <b>dh</b> is NULL nothing is done.</p>

|
|
||
|
|
<h1 id="RETURN-VALUES">RETURN VALUES</h1>
|
||
|
|
|
||
|
|
<p>If the allocation fails, DH_new() returns <b>NULL</b> and sets an error code that can be obtained by <a href="../man3/ERR_get_error.html">ERR_get_error(3)</a>. Otherwise it returns a pointer to the newly allocated structure.</p>
|
||
|
|
|
||
|
|
<p>DH_free() returns no value.</p>
