.Sh NAME
.Nm isgraph
.Nd printing character test (space character exclusive)
.Sh LIBRARY
.Lb libc
.Sh SYNOPSIS
.Fd #include <ctype.h>
.Ft int
.Fn isgraph "int c"
.Sh DESCRIPTION
The
.Fn isgraph
function tests for any printing character except space.
For single C
.Va char Ns s
locales (see
.Xr multibyte 3 )
the value of the argument is
representable as an
.Li unsigned char
or the value of
.Dv EOF .
In the ASCII character set, this includes the following characters
(with their numeric values shown in octal):
.Pp
