So for example B<type> can be set to +B<MBSTRING_ASC> but in the case of X509_set_data() the field name must be +set first so the relevant field information can be looked up internally. + +=head1 RETURN VALUES + +X509_NAME_ENTRY_get_object() returns a valid B<ASN1_OBJECT> structure if it is +set or NULL if an error occurred. + +X509_NAME_ENTRY_get_data() returns a valid B<ASN1_STRING> structure if it is set +or NULL if an error occurred. + +X509_NAME_ENTRY_set_object() and X509_NAME_ENTRY_set_data() return 1 on success +or 0 on error. + +X509_NAME_ENTRY_create_by_txt(), X509_NAME_ENTRY_create_by_NID() and +X509_NAME_ENTRY_create_by_OBJ() return a valid B<X509_NAME_ENTRY> on success or +NULL if an error occurred. + +=head1 SEE ALSO + +L<ERR_get_error(3)>, L<d2i_X509_NAME(3)>, +L<OBJ_nid2obj(3)> + +=head1 COPYRIGHT + +Copyright 2002-2018 The OpenSSL Project Authors.
