## Struct template pointer_plus_bit<T *>

boost::intrusive::pointer_plus_bit<T *>

## Synopsis

    template<typename T>
    struct pointer_plus_bit<T *> {
      // types
      typedef T * pointer;

      // public static functions
      static pointer get_pointer(pointer) ;
      static void set_pointer(pointer &, pointer) ;
      static bool get_bit(pointer) ;
      static void set_bit(pointer &, bool) ;
    };

## Description

This is the specialization to embed an extra bit of information in a raw pointer. The extra bit is stored in the lower bit of the pointer.

### `pointer_plus_bit` public static functions

1.     static pointer get_pointer(pointer n) ;

2.     static void set_pointer(pointer & n, pointer p) ;

3.     static bool get_bit(pointer n) ;

4.     static void set_bit(pointer & n, bool c) ;
