/*
* This is the header where the internal to libc definition of the FILE
* structure is defined. The exrernal defintion defines the FILE structure
* as an array of longs. This prevents customers from writing code that
* depends upon the implemnetation of stdio. The __fbufsize(3C) man page
* documents a set of routines that customers can use so that they do not
* need access to the FILE structure.
*
* When compiling libc this file MUST be included BEFORE <stdio.h>, and
* any other headers that themselves directly or indirectly include
* <stdio.h>. Failure to do so, will cause the compile of libc to fail,
* since the structure members will not be visible to the stdio routines.
