@var{resp}: should contain a @code{gnutls_ocsp_resp_t}  type

@var{indx}: Specifies response number to get. Use (0) to get the first one.

@var{digest}: output variable with @code{gnutls_digest_algorithm_t}  hash algorithm

@var{issuer_name_hash}: output buffer with hash of issuer's DN

@var{issuer_key_hash}: output buffer with hash of issuer's public key

@var{serial_number}: output buffer with serial number of certificate to check

@var{cert_status}: a certificate status, a @code{gnutls_ocsp_cert_status_t}  enum.

@var{this_update}: time at which the status is known to be correct.

@var{next_update}: when newer information will be available, or (time_t)-1 if unspecified

@var{revocation_time}: when  @code{cert_status} is @code{GNUTLS_OCSP_CERT_REVOKED} , holds time of revocation.

@var{revocation_reason}: revocation reason, a @code{gnutls_x509_crl_reason_t}  enum.

This function will return the certificate information of the
 @code{indx} 'ed response in the Basic OCSP Response  @code{resp} .  The
information returned corresponds to the OCSP SingleResponse structure
except the final singleExtensions.

Each of the pointers to output variables may be NULL to indicate
that the caller is not interested in that value.

@strong{Returns:} On success, @code{GNUTLS_E_SUCCESS}  (0) is returned, otherwise a
negative error code is returned.  If you have reached the last
CertID available @code{GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE}  will be
returned.
