/**
* SECTION: field
* @title: Field
* @short_description: description of the partition fields
*
* The fdisk fields are static user-friendly descriptions of the partition. The
* fields are used to avoid label specific stuff in the functions that list disk
* partitions (e.g. fdisk -l). The field Id is the same as Id for fdisk_partition_to_string().
*
* <informalexample>
* <programlisting>
* int *ids;
* size_t nids;
* struct fdisk_partition *pa = NULL;
* struct fdisk_label *lb = fdisk_get_label(cxt, NULL);
*
* fdisk_label_get_fields_ids(lb, cxt, &ids, &nids);
*
* fdisk_get_partition(cxt, 0, &pa);
*
* for (i = 0; i < nids; i++) {
* const struct fdisk_field *field = fdisk_label_get_field(lb, ids[i]);
*
* int id = fdisk_field_get_id(fl);
* const char *name = fdisk_field_get_name(fl);
* char *data;
*
* fdisk_partition_to_string(pa, id, &data);
* printf("%s: %s\n", name, data);
* free(data);
* }
* free(ids);
* </programlisting>
* </informalexample>
*
* This example lists all information about the first partition. It will work
* for MBR as well as for GPT because fields are not hardcoded in the example.
*
* See also fdisk_label_get_field_by_name(), fdisk_label_get_fields_ids_all()
* and fdisk_label_get_fields_ids().
