7.1.7 Nonstandard Header Files in the Source Tree
The source code in the lib/src subdirectory of the compiler installation contains these non-ANSI include files that are used to build the library:
- The values.h file contains the definitions necessary for recompiling the trigonometric and transcendental math functions. If necessary, you can customize the functions in values.h.
- The file.h file includes macros and definitions used for low-level I/O functions.
- The format.h file includes structures and macros used in printf and scanf.
- The 470cio.h file includes low-level, target-specific C I/O macro definitions. If necessary, you can customize 470cio.h.
- The rtti.h file includes internal function prototypes necessary to implement run-time type identification.
- The vtbl.h file contains the definition of a class's virtual function table format.
