Command Line Options
The compiler, like the other tools in ZDS II, can be run from the command line for pro-
cessing inside a script, and so on. Please see
Compiler Command Line Options on
page 354 for the list of compiler commands that are available from the command line.
Run-Time Library
The C-Compiler provides a collection of run-time libraries. The largest section of these
libraries consists of an implementation of much of the C Standard Library. A small library
of functions specific to Zilog or to the ZNEO is also provided.
The ZNEO C-Compiler is a conforming freestanding 1989 ANSI C implementation with
some exceptions. In accordance with the definition of a freestanding implementation, the
compiler supports the required standard header files <
float.h >, < limits.h >,
< stdarg.h >, and < stddef.h >. It also supports additional standard header files and
Zilog-specific nonstandard header files.
The standard header files and functions are, with minor exceptions, fully compliant with
the ANSI C Standard. They are described in detail in the appendix titled
C Standard
Library , on page 391. The deviations from the ANSI Standard in these files are summa-
rized in the Library Files Not Required for Freestanding Implementation section on
page 196. The following sections describe the use and format of the nonstandard, Zilog-
specific run-time libraries:
•
Zilog Header Files – see page 178
•
Zilog Functions – see page 180

The Zilog-specific header files provided with the compiler are listed in Table 13 and
described in the
Zilog Header Files section on page 178.
