## Detailed Description

Classes and functions for internationalization and localization.

## Function Documentation

## has_facet()

template<typename _Facet >

bool std::has_facet | ( | const locale & | __loc | ) |
throw | ( |
| ) |  |

Test for the presence of a facet.

has_facet tests the locale argument for the presence of the facet type provided as the template parameter. Facets derived from the facet parameter will also return true.

Template Parameters

  _Facet | The facet type to test the presence of.

Parameters

  __loc | The locale to test.

Returns
  true if `__loc` contains a facet of type _Facet, else false.

## use_facet()

template<typename _Facet >

const _Facet & std::use_facet | ( | const locale & | __loc | ) |

Return a facet.

use_facet looks for and returns a reference to a facet of type Facet where Facet is the template parameter. If has_facet(locale) is true, there is a suitable facet to return. It throws std::bad_cast if the locale doesn't contain a facet of type Facet.

Template Parameters

  _Facet | The facet type to access.

Parameters

  __loc | The locale to use.

Returns
  Reference to facet of type Facet.

Exceptions

  std::bad_cast | if `__loc` doesn't contain a facet of type _Facet.
