 NAME

   new -	The new	operators (used	to allocate dynamic storage in a program)
   are declared in the header <new>.

 SYNOPSIS

   #include <new>

   void *operator new(size_t n) throw(std::bad_alloc);

   void *operator new(size_t n, const std::nothrow_t&) throw();

   void *operator new(size_t n, void *p)	throw();

   void *operator new[](size_t n) throw(std::bad_alloc);

   void *operator new[](size_t n,const std::nothrow_t&) throw();

   void *operator new[](size_t n, void *p) throw();

 DESCRIPTION

   void *operator new(size_t n) throw(std::bad_alloc);
   void *operator new(size_t n, const std::nothrow_t&) throw()

   These	versions of new	are called to allocate n bytes of suitably
   aligned storage to represent an object of that size.	A C++ program
   can define a function with	either of these	signatures which is
   intended to	replace	the implementation provided default provided
   by the Standard C++ Library.	 Both return a non-null pointer when
   memory	allocation succeeds.  The first	function throws
   bad_alloc	on memory allocation failure.  The second or nothrow
   version of operator new returns null on memory allocation failure.

   void *operator new(size_t n, void *p)	throw();

   This function	is called by a placement new expression	which looks
   like new (p) T, where p is a pointer to an object.  The function
   returns p.

   void *operator new[](size_t n) throw(std::bad_alloc); void *operator
   new[](size_t n,const std::nothrow_t&) throw();

   The next two functions are called by a new[] expression i.e. by the
   array form of a new	expression.  They are called to	allocate n
   bytes  of suitably aligned storage to represent an array	object
   of that  or smaller size. A C++ program can define a function with
   either of these signatures which is intended to replace the default
   implementation provided by the Standard C++ Library.  Both return
   a non-null pointer when memory allocation succeeds.  The first
   function throws bad_alloc on memory	allocation failure.  The
   second or nothrow version of operator	new returns null on memory
   allocation failure.

   void *operator new[](size_t n, void *p) throw();

   This function	is called by a placement array new expression which
   looks like new (p) T[n], where p is	a pointer to an	object.	  The
   function returns p.
