Name

locale::category type — Bitmask of facet categories

Synopsis

typedef int category;
static const category
  none, collate, ctype, monetary, numeric, time, messages,
  all = collate|ctype|monetary|numeric|time|messages;

The category type is an int and represents a bitmask of category identifiers, as listed in Table 13-21. Each category represents a set of one or more related facets. When combining locales, you can copy all the facets in one or more categories. Category identifiers can be combined using bitwise operators.
