 NAME

   isalnum - Determines if a character is alphabetic or numeric.

 SYNOPSIS

   #include <locale>
   template <class charT>

   bool isalnum (charT c, const locale& loc) const;

 DESCRIPTION

   The isalnum function returns true if the character passed as a
   parameter is either part of the alphabet specified	by the locale
   parameter	or a decimal digit, otherwise the function
   returns	false.	 The check is made using the ctype	facet
   from the locale parameter.

 EXAMPLE

   //
   // isalnum.cpp
   //

   #include <iostream>

   int main ()
   {
    using namespace std;

    locale loc;

    cout	<< isalnum('a',loc) << endl;
    cout	<< isalnum(',',loc) << endl;

    return 0;
   }
