.Sh SYNOPSIS
|
|
.In ctype.h
|
|
.Ft int
|
|
.Fn isgraph "int c"
|
|
.Ft int
|
|
.Fn isgraph_l "int c" "locale_t loc"
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Fn isgraph
|
|
and
|
|
.Fn isgraph_l
|
|
functions test for any printing character except space
|
|
.Pq Ql "\~"
|
|
and other
|
|
locale-specific space-like characters.
|
|
The value of the argument must be representable as an
|
|
.Vt "unsigned char"
|
|
or the value of
|
|
.Dv EOF .
|
|
.Pp
|
|
In the ASCII character set, this includes the following characters
|
|
(with their numeric values shown in octal):
|
|
.Bl -column \&000_``0''__ \&000_``0''__ \&000_``0''__ \&000_``0''__ \&000_``0''__

.El
|
|
.Pp
|
|
The
|
|
.Fn isgraph_l
|
|
function takes an explicit locale argument, whereas the
|
|
.Fn isgraph
|
|
function uses the current global or per-thread locale.
|
|
.Sh RETURN VALUES
|
|
The
|
|
.Fn isgraph
|
|
and
|
|
.Fn isgraph_l
|
|
functions return zero if the character tests false and
|
|
return non-zero if the character tests true.
|
|
.Sh COMPATIBILITY
|
|
The
|
|
.Bx 4.4
|
|
extension of accepting arguments outside of the range of the
|
|
.Vt "unsigned char"
|
|
type in locales with large character sets is considered obsolete
|
|
and may not be supported in future releases.
|
|
The
|
|
.Fn iswgraph
|
|
or
|
|
.Fn iswgraph_l
|
|
function should be used instead.
