DESCRIPTION
     These functions decode and encode X.509 extensions that communicate where
     to retrieve additional information online.  For details about the
     semantics, examples, caveats, and bugs, see ASN1_item_d2i(3).

     d2i_DIST_POINT() and i2d_DIST_POINT() decode and encode an ASN.1
     DistributionPoint structure defined in RFC 5280 section 4.2.1.13.

     d2i_CRL_DIST_POINTS() and i2d_CRL_DIST_POINTS() decode and encode an
     ASN.1 CRLDistributionPoints structure defined in RFC 5280 section
     4.2.1.13.

     d2i_DIST_POINT_NAME() and i2d_DIST_POINT_NAME() decode and encode an
     ASN.1 DistributionPointName structure defined in RFC 5280 section
     4.2.1.13.

     d2i_ISSUING_DIST_POINT() and i2d_ISSUING_DIST_POINT() decode and encode
     an ASN.1 IssuingDistributionPoint structure defined in RFC 5280 section
     5.2.5.

     d2i_ACCESS_DESCRIPTION() and i2d_ACCESS_DESCRIPTION() decode and encode
     an ASN.1 AccessDescription structure defined in RFC 5280 section 4.2.2.1.

     d2i_AUTHORITY_INFO_ACCESS() and i2d_AUTHORITY_INFO_ACCESS() decode and
     encode an ASN.1 AuthorityInfoAccessSyntax structure defined in RFC 5280
     section 4.2.2.1.

RETURN VALUES
     d2i_DIST_POINT(), d2i_CRL_DIST_POINTS(), d2i_DIST_POINT_NAME(),
     d2i_ISSUING_DIST_POINT(), d2i_ACCESS_DESCRIPTION(), and
     d2i_AUTHORITY_INFO_ACCESS() return an object of the respective type or
     NULL if an error occurs.

     i2d_DIST_POINT(), i2d_CRL_DIST_POINTS(), i2d_DIST_POINT_NAME(),
     i2d_ISSUING_DIST_POINT(), i2d_ACCESS_DESCRIPTION(), and
     i2d_AUTHORITY_INFO_ACCESS() return the number of bytes successfully
     encoded or a negative value if an error occurs.
