The id member variable of a facet class cannot be accessed directly in Open C++. Instead, it has to be accessed via the GetFacetLocaleId() interface.

Solution

The following code snippet demonstrates how to use locale::id when writing an application on top of the Standard Template Library (STL).

Declare a static method GetFacetLocaleId() instead of the member variable id, when defining a class which is inherited from class locale::facet.

  // b_facet.h 
class base_facet : public locale::facet 
  { 
public: 
  static locale::id& GetFacetLocaleId(); // in place of static locale::id
  };

In the source file, define the method GetFacetLocaleId():

// b_facet.cpp
locale::id base_facet_id; 
locale::id& base_facet::GetFacetLocaleId()
    { 
    return base_facet_id; 
    }
