For details about the semantics, examples, caveats, and bugs, see .Xr ASN1_item_d2i 3 . .Pp .Fn d2i_PROXY_POLICY and .Fn i2d_PROXY_POLICY decode and encode an ASN.1 .Vt ProxyPolicy structure defined in RFC 3820 section 3.8. .Pp .Fn d2i_PROXY_CERT_INFO_EXTENSION and .Fn i2d_PROXY_CERT_INFO_EXTENSION decode and encode an ASN.1 .Vt ProxyCertInfo structure defined in RFC 3820 section 3.8. .Sh RETURN VALUES .Fn d2i_PROXY_POLICY and .Fn d2i_PROXY_CERT_INFO_EXTENSION return a .Vt PROXY_POLICY or .Vt PROXY_CERT_INFO_EXTENSION object, respectively, or .Dv NULL if an error occurs. .Pp .Fn i2d_PROXY_POLICY and .Fn i2d_PROXY_CERT_INFO_EXTENSION return the number of bytes successfully encoded or a negative value if an error occurs. .Sh SEE ALSO .Xr ASN1_item_d2i 3 , .Xr PROXY_POLICY_new 3 , .Xr X509_EXTENSION_new 3 .Sh STANDARDS RFC 3820: Internet X.509 Public Key Infrastructure (PKI) Proxy Certificate Profile .Sh HISTORY These functions first appeared in OpenSSL 0.9.7g and have been available since .Ox 3.8 .
