fcloseall()              Close All Open Streams
 
 #include   <stdio.h>
 
 int        fcloseall(void);
 
    fcloseall() closes all open streams except 'stdin', 'stdout',
    'stderr', 'stdaux', and 'stdprn'.  All buffers associated with the
    streams are flushed before being closed.  System-allocated buffers
    are freed when the stream is closed.
 
 
    Returns:    The total number of streams successfully closed.  EOF is
                returned on error.
 
      Notes:    Buffers assigned by setbuf() are not automatically freed.
 
  -------------------------------- Example ---------------------------------
 
    This example opens two streams and closes them both with a single
    call to fcloseall().
 
         #include <stdio.h>
 
         FILE *stream1, *stream2;
 
         main()
         {
             if ((stream1 = fopen("ch1.txt","r+")) != NULL &&
                 (stream2 = fopen("ch2.txt","r+")) != NULL)
                 .
                 .
                 .
                 fcloseall();
              }
          }
