  static int xalloc();
 
  Remarks
 
  Provides extra ios object state variables without the need for class
  derivation. It does so by returning an index to an unused 32-bit word in
  an internal array. This index can be subsequently converted into a
  reference or pointer by using the iword or pword member functions.
 
  Any call to xalloc invalidates values returned by previous calls to
  iword and pword.
