+
+=head1 DESCRIPTION
+
+X509_CRL_get0_by_serial() attempts to find a revoked entry in B<crl> for
+serial number B<serial>. If it is successful it sets B<*ret> to the internal
+pointer of the matching entry, as a result B<*ret> must not be freed up
+after the call.
+
+X509_CRL_get0_by_cert() is similar to X509_get0_by_serial() except it
+looks for a revoked entry using the serial number of certificate B<x>.
+
+X509_CRL_get_REVOKED() returns an internal pointer to a stack of all
+revoked entries for B<crl>.
+
+X509_REVOKED_get0_serialNumber() returns an internal pointer to the
+serial number of B<r>.
+
+X509_REVOKED_get0_revocationDate() returns an internal pointer to the
+revocation date of B<r>.
+
+X509_REVOKED_set_serialNumber() sets the serial number of B<r> to B<serial>.
+The supplied B<serial> pointer is not used internally so it should be
+freed up after use.
+
+X509_REVOKED_set_revocationDate() sets the revocation date of B<r> to
+B<tm>. The supplied B<tm> pointer is not used internally so it should be
+freed up after use.
+
+X509_CRL_add0_revoked() appends revoked entry B<rev> to CRL B<crl>. The
+pointer B<rev> is used internally so it must not be freed up after the call:
+it is freed when the parent CRL is freed.
+
+X509_CRL_sort() sorts the revoked entries of B<crl> into ascending serial
+number order.
+
+=head1 NOTES
+
+Applications can determine the number of revoked entries returned by
+X509_CRL_get_revoked() using sk_X509_REVOKED_num() and examine each one
+in turn using sk_X509_REVOKED_value().
+
+=head1 RETURN VALUES
+
+X509_CRL_get0_by_serial(), X509_CRL_get0_by_cert(),
+X509_REVOKED_set_serialNumber(), X509_REVOKED_set_revocationDate(),
+X509_CRL_add0_revoked() and X509_CRL_sort() return 1 for success and 0 for
+failure.
+
+X509_REVOKED_get0_serialNumber() returns an B<ASN1_INTEGER> pointer.
+
+X509_REVOKED_get0_revocationDate() returns an B<ASN1_TIME> value.
+
+X509_CRL_get_REVOKED() returns a STACK of revoked entries.
