#include <ctype.h>
int isgraph(int c);
The isgraph() function tests for any printing character
except the space character, that is, any character for which
isalnum() or ispunct() is true.
The behavior of the isgraph()
function is affected by the current locale. To modify the
behavior, change the LC_CTYPE category in
setlocale(), that is,
setlocale(LC_CTYPE, newlocale). In the C locale
or in a locale where character type information is not defined,
characters are classified according to the rules of the U.S.
ASCII 7-bit coded character set.

Is an integer whose value is representable as an unsigned char,

The isgraph() function
returns non-zero for true and zero for false. If the parameter is
not in the domain of the function, the return result is undefined.
ANSI/ISO 9899-1990.
