locale::category

An integer type that provides bitmask values to denote standard facet families.

typedef int category;
static const int collate = LC_COLLATE;
static const int ctype = LC_CTYPE;
static const int monetary = LC_MONETARY;
static const int numeric = LC_NUMERIC;
static const int time = LC_TIME;
static const int messages = LC_MESSAGES;
static const int all = LC_ALL;
static const int none = 0;

Remarks

The type is a synonym for an int type that can represent a group of distinct elements of a bitmask type local to class locale or can be used to represent any of the corresponding C locale categories. The elements are:

  • collate, corresponding to the C category LC_COLLATE

  • ctype, corresponding to the C category LC_CTYPE

  • monetary, corresponding to the C category LC_MONETARY

  • numeric, corresponding to the C category LC_NUMERIC

  • time, corresponding to the C category LC_TIME

  • messages, corresponding to the Posix category LC_MESSAGES

In addition, two useful values are:

  • none, corresponding to none of the C categories

  • all, corresponding to the C union of all categories LC_ALL

You can represent an arbitrary group of categories by using OR with these constants, as in monetary | time.
