Chapter 8 ANSI Library
This chapter explains the ANSI library included in the S1C33 Family C Compiler Package.
8.1 Overview
The S1C33 Family C Compiler Package contains an ANSI library.
Each function in this library has ANSI-standard functionality. However, some file-related functions are dummy
functions due to embedded microcomputer specifications.
There are five types of ANSI library files, which are installed in the lib directory.
io.lib lib.lib math.lib ctype.lib string.lib
In addition, the following header files which contain definitions of each function are installed in the include
directory.
stdio.h stdlib.h time.h math.h errno.h float.h limits.h ctype.h string.h stdarg.h
Refer to the sample file located in the "cc33\sample\ansilib\" directory for how to use the library functions..
All source codes are located in the "cc33\utility\lib_src\" directory. Refer to the source for more information and
modify them if needed.
Note: When specifying library files including emulation library files (fp.lib, idiv.lib) during linkage, please
S5U1C33000C MANUAL
(C COMPILER PACKAGE FOR S1C33 FAMILY) (Ver. 4)
follow the specification priority shown below:
io.lib lib.lib math.lib ctype.lib string.lib fp.lib idiv.lib
The file io.lib contains functions that call the lib.lib or math.lib functions. Also, lib.lib calls the
math.lib functions. Reference between library files is only valid for functions in the library file that
is specified later. Therefore, if library files are arranged in a different order, a warning may be
generated during linkage.
