Tailoring input/output functions in the C and C++ libraries

High-level input/output, such as the functions fscanf() and fprintf(), and the C++ object std::cout, 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.

For more information on I/O functions, see the rt_sys.h file in install_directory\RVCT\Data\...\include.
