* Selector descriptor
*
* A selector describes an attribute of some context object.
- * A selector with ca_type NSC_NOTYPE is invalid.
- * If ca_get is null, the selector describes a datum of type ca_type
- * at offset ca_offs in the context object.
- * A datum of type NSC_STRINGY is an array of ca_len characters.
+ * A selector with @ca_type NSC_NOTYPE is invalid.
+ * If @ca_get is null, the selector describes a datum of type @ca_type
+ * at offset @ca_offs in the context object.
+ * A datum of type NSC_STRINGY is a string stored in an array of
+ * @ca_len characters. Ugly wart: if @ca_len is one, the terminating
+ * null character may be omitted.
* A datum of any other type is either a scalar of that type (if
- * ca_len is zero), or an array of ca_len elements of that type.
- * If ca_get is not null, the selector is virtual. Values can be
- * obtained by calling ca_get(VAL, NP, CTXO), where VAL has been
+ * @ca_len is zero), or an array of @ca_len elements of that type.
+ * If @ca_get is not null, the selector is virtual. Values can be
+ * obtained by calling @ca_get(VAL, NP, CTXO), where VAL has been
* initialized from the selector and an index by nstr_mksymval(),
* NP points to the country to use for coordinate translation and
* access control (null for none), and CTXO is the context object.
* See struct valstr for details.
* Because virtual selectors don't have a setter method, xundump must
- * be made to ignore them, by setting NSC_EXTRA.
- * If flag NSC_DEITY is set, only to deities can use this selector.
- * If flag NSC_EXTRA is set, xdump and xundump ignore this selector.
- * If flag NSC_CONST is set, the datum can't be changed from its
- * initial value (xundump obeys that).
- * If ca_table is not EF_BAD, the datum refers to that Empire table;
- * ca_type must be an integer type. If flag NSC_BITS is set, the
- * datum consists of flag bits, and the referred table must be a
- * symbol table defining those bits.
+ * be made to ignore them, by setting @ca_dump to CA_DUMP_NONE.
+ * If @ca_table is not EF_BAD, the datum refers to that Empire table;
+ * @ca_type must be an integer type.
+ * If NSC_BITS is set in @ca_flags, the datum consists of flag bits,
+ * and the referred table must be a symbol table defining those bits.
+ * If NSC_DEITY is set in @ca_flags, only deities can use this
