 NAME

   has_facet - A	function template used to determine if a locale	has a
   given facet.

 SYNOPSIS

   #include <locale>
   template <class Facet> bool has_facet(const locale&) throw();

 DESCRIPTION

   has_facet returns true if the	requested facet	is available in	the
   locale, otherwise it returns false.	You specify the	facet type by
   explicitly providing the template parameter. (See the example
   below.)

      Note that if your compiler cannot overload function templates
      on return type then you'll need	to use an alternative
      has_facet	template.  The alternative template takes	an
      additional argument that's a	pointer	to the type of facet
      you want to check on.  The declaration looks	like this:

   template <class Facet>
   const	bool has_facet(const locale&, Facet*) throw();

   The example below shows the use of both variations of	has_facet.

 EXAMPLE

   //
   // hasfacet.cpp
   //

   #include <iostream>

   int main ()
   {
    using namespace std;

    locale loc;

   #ifndef _RWSTD_NO_TEMPLATE_ON_RETURN_TYPE
    cout	<< has_facet<ctype<char> >(loc)	<< endl;
   #else
    cout	<< has_facet(loc,(ctype<char>*)0) << endl;
   #endif

    return 0;
   }
