int isgraph (char c);
int isgraph_l (int c, locale_t locale);- DESCRIPTION
-
Checks if the given character has a graphical representation, i.e. it is either a number (
0123456789), an uppercase letter (ABCDEFGHIJKLMNOPQRSTUVWXYZ), a lowercase letter (abcdefghijklmnopqrstuvwxyz), or a punctuation character(!"#$%&'()*+,-./:;<⇒?@[\]^_{|}~`), or any graphical character specific to the current C locale.
The behavior is undefined if the value of c is not representable as
unsigned char and is not equal to EOF.
