<h1><a name="description">DESCRIPTION</a></h1>
<p>PKCS8_pkey_get0_attrs() returns a const STACK of X509_ATTRIBUTE present in
the passed const PKCS8_PRIV_KEY_INFO structure <strong>p8</strong>.</p>
<p>PKCS8_pkey_add1_attr() adds a constructed X509_ATTRIBUTE <strong>attr</strong> to the
existing PKCS8_PRIV_KEY_INFO structure <strong>p8</strong>.</p>
<p>PKCS8_pkey_add1_attr_by_NID() and PKCS8_pkey_add1_attr_by_OBJ() construct a new
X509_ATTRIBUTE from the passed arguments and add it to the existing
PKCS8_PRIV_KEY_INFO structure <strong>p8</strong>.</p>
<p>
</p>
<hr />
<h1><a name="return_values">RETURN VALUES</a></h1>
<p>PKCS8_pkey_add1_attr(), PKCS8_pkey_add1_attr_by_NID(), and
PKCS8_pkey_add1_attr_by_OBJ() return 1 for success and 0 for failure.</p>
<p>
</p>
<hr />
<h1><a name="notes">NOTES</a></h1>
<p>STACK of X509_ATTRIBUTE is present in many X509-related structures and some of
them have the corresponding set of similar functions.</p>
