DESCRIPTION
     These functions decode and encode ASN.1 structures used for OCSP
     requests.  For details about the semantics, examples, caveats, and bugs,
     see ASN1_item_d2i(3).

     d2i_OCSP_REQUEST() and i2d_OCSP_REQUEST() decode and encode an ASN.1
     OCSPRequest structure defined in RFC 6960 section 4.1.1.

     d2i_OCSP_SIGNATURE() and i2d_OCSP_SIGNATURE() decode and encode an ASN.1
     Signature structure defined in RFC 6960 section 4.1.1.

     d2i_OCSP_REQINFO() and i2d_OCSP_REQINFO() decode and encode an ASN.1
     TBSRequest structure defined in RFC 6960 section 4.1.1.

     d2i_OCSP_ONEREQ() and i2d_OCSP_ONEREQ() decode and encode an ASN.1
     Request structure defined in RFC 6960 section 4.1.1.

     d2i_OCSP_CERTID() and i2d_OCSP_CERTID() decode and encode an ASN.1 CertID
     structure defined in RFC 6960 section 4.1.1.

     d2i_OCSP_SERVICELOC() and i2d_OCSP_SERVICELOC() decode and encode an
     ASN.1 ServiceLocator structure defined in RFC 6960 section 4.4.6.

RETURN VALUES
     d2i_OCSP_REQUEST(), d2i_OCSP_SIGNATURE(), d2i_OCSP_REQINFO(),
     d2i_OCSP_ONEREQ(), d2i_OCSP_CERTID(), and d2i_OCSP_SERVICELOC() return an
     object of the respective type or NULL if an error occurs.

     i2d_OCSP_REQUEST(), i2d_OCSP_SIGNATURE(), i2d_OCSP_REQINFO(),
     i2d_OCSP_ONEREQ(), i2d_OCSP_CERTID(), and i2d_OCSP_SERVICELOC() return
     the number of bytes successfully encoded or a negative value if an error
     occurs.
