So for example B<type> can be set to 64B<MBSTRING_ASC> but in the case of X509_set_data() the field name must be 65set first so the relevant field information can be looked up internally. 66 67=head1 RETURN VALUES 68 69X509_NAME_ENTRY_get_object() returns a valid B<ASN1_OBJECT> structure if it is 70set or NULL if an error occurred. 71 72X509_NAME_ENTRY_get_data() returns a valid B<ASN1_STRING> structure if it is set 73or NULL if an error occurred. 74 75X509_NAME_ENTRY_set_object() and X509_NAME_ENTRY_set_data() return 1 on success 76or 0 on error. 77 78X509_NAME_ENTRY_create_by_txt(), X509_NAME_ENTRY_create_by_NID() and 79X509_NAME_ENTRY_create_by_OBJ() return a valid B<X509_NAME_ENTRY> on success or 80NULL if an error occurred. 81 82=head1 SEE ALSO 83 84L<ERR_get_error(3)>, L<d2i_X509_NAME(3)>, 85L<OBJ_nid2obj(3)> 86 87=head1 COPYRIGHT 88 89Copyright 2002-2018 The OpenSSL Project Authors.
