<P>
<CODE>SSL_CTX_add_extra_chain_cert()</CODE> adds the certificate <STRONG>x509</STRONG> to the certificate chain presented together with the certificate. Several
certificates can be added one after the other.

When constructing the certificate chain, the chain will be formed from
these certificates explicitly specified. If no chain is specified, the
library will try to complete the chain from the available CA certificates
in the trusted CA storage, see
<A HREF="../ssl/SSL_CTX_load_verify_locations.html#">SSL_CTX_load_verify_locations(3)</A>.

<CODE>SSL_CTX_add_extra_chain_cert()</CODE> returns 1 on success. Check out
the error stack to find out the reason for failure otherwise.
