const _Facet & use_facet const locale &  __loc  )  [inline]
 

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.

Parameters:
Facet The facet type to access.
locale The locale to use.
Returns:
Reference to facet of type Facet.
Exceptions:
std::bad_cast if locale doesn't contain a facet of type Facet.
