| /*******************

 | |
|  * Copyright 1998-2010 IAR Systems AB.  
 | |
|  *
 | |
|  * This is a template implementation of the "__write" function used by
 | |
|  * the standard library.  Replace it with a system-specific
 | |
|  * implementation.
 | |
|  *
 | |
|  * The "__write" function should output "size" number of bytes from
 | |
|  * "buffer" in some application-specific way.  It should return the
 | |
|  * number of characters written, or _LLIO_ERROR on failure.
 | |
|  *
 | |
|  * If "buffer" is zero then __write should perform flushing of
 | |
|  * internal buffers, if any.  In this case "handle" can be -1 to
 | |
|  * indicate that all handles should be flushed.
 | |
|  *
 | |
|  * The template implementation below assumes that the application
 | |
|  * provides the function "MyLowLevelPutchar".  It should return the
 | |
|  * character written, or -1 on failure.
