Warner Losh fbbd9655e5 Renumber copyright clause 4
Renumber cluase 4 to 3, per what everybody else did when BSD granted
them permission to remove clause 3. My insistance on keeping the same
numbering for legal reasons is too pedantic, so give up on that point.

.Sh NAME
.Nm isprint
.Nd printing character test (space character inclusive)
.Sh LIBRARY
.Lb libc
.Sh SYNOPSIS
.In ctype.h
.Ft int
.Fn isprint "int c"
.Sh DESCRIPTION
The
.Fn isprint
function tests for any printing character, including space
.Pq Ql "\ " .
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''__

.Sh RETURN VALUES
The
.Fn isprint
function returns zero if the character tests false and
returns 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 iswprint
function should be used instead.
.Sh SEE ALSO
.Xr ctype 3 ,
.Xr iswprint 3 ,
.Xr ascii 7
.Sh STANDARDS
The
.Fn isprint
function conforms to
.St -isoC .
