The higher-level input/output functions such as fscanf() and fprintf() are not target-dependent. However, the higher-level functions perform input/output by calling lower-level functions that are target-dependent. To retarget input/output, you can either avoid these higher-level functions or redefine the lower-level functions.

See the rt_sys.h include file for more information on I/O functions.
