Zilog Developer Studio II – Z8 Encore!

compiler such as the Z8 Encore! C-Compiler. However, the compiler does support many
of the other standard library headers as well. The supported headers are listed here. The
support offered in the Zilog libraries is fully compliant with the standard except as noted
here:
•
< assert.h >
•
< ctype.h >
•
< errno.h >
•
< math.h >
The Zilog implementation of this library is not fully ANSI compliant in the general
limitations of the handling of floating-point numbers: namely, Zilog does not fully
support floating-point NANs, INFINITYs, and related special values. These special
values are part of the full ANSI/IEEE 754-1985 floating-point standard that is refer-
enced in the ANSI C Standard.
•
< stddef.h >
•
< stdio.h >
Zilog supports only the portions of stdio.h that make sense in the embedded envi-
ronment. Specifically, Zilog defines the ANSI required functions that do not depend
on a file system. For example,
printf and sprintf are supplied but not fprintf .
•
< stdlib.h >
This header is ANSI compliant in the Zilog library except that the following functions
of limited or no use in an embedded environment are not supplied:
strtoul()

_Exit()

atexit()
