FILE LIST -
             teststdio.c

DESCRIPTION -
	     The following functions fopen, fclose and freopen have been
	     tested here.
	     fopen() - This is used to open a file. fopen returns a pointer
	     to the beginning of the buffer area associated with the file or a
	     NULL if the file cannot be opened.
	     fclose() - A data file must always be closed at the end of 
             a program and this is achieved using the fclose function.
	     freopen() - This is used to attach preopened streams to other 
             files.

RUNNING DEMO - 
	     Place the teststdio.c in your <Tornado> dir.
	     Depending on the target you have, define the 
	     CPU in your compile line and use the Makefile
	     in the BSP dir. to compile.

	     Run teststdio() on vxworks target.

TESTED ON -  Host/Target : Solaris 2.5.1 /mv1604
	     VxWorks     : 5.3.1

EXAMPLE COMPILE LINE - 
             make CPU=PPC604 teststdio.o		    
			      
% make teststdio.o

OUTPUTS/LOGFILE -

On VxWorks target:
==================

-> ld <teststdio.o
value = 839784 = 0xcd068
-> teststdio()
value = 0 = 0x0

The Output on Console:
======================
Success testing stdio
