BZZZZT!
There is no such thing as isascii() in Standard C. The domain of all
of the ctype(3) functions, as Bruce noted earlier in this thread, is
[UCHAR_MIN,UCHAR_MAX] union {EOF}.
wollman@khavrinen(173)$ cat >foo.c
#include <ctype.h>
#include <limits.h>
#include <stdio.h>
int
main(void)
{
int c;
for (c = UCHAR_MIN; c < UCHAR_MAX; c++) {
if (ispunct(c))
putchar(c);
}
putchar('\n');
if (ispunct(EOF))
printf("EOF\n");
return 0;
}
wollman@khavrinen(174)$ cc -o foo foo.c
wollman@khavrinen(175)$ ./foo
!"#$%&'()*+,-./:;<=>?@[\]^_`{|}~¡¢£¤¥¦§¨©ª«¬®¯°±²³´µ¶·¸¹º»¼½¾¿×÷

In case you can't read the high-bit characters there, they are all the
punctuation characters from the ISO 8859-1 (``Latin 1'') character
set.
