NAME
     isprint -- printing character test (space character inclusive)

LIBRARY
     Standard C Library (libc, -lc)

SYNOPSIS
     #include <ctype.h>

     int
     isprint(int c);

DESCRIPTION
     The isprint() function tests for any printing character including space
     (' ').  For single C chars locales the value of the argument is repre-
     sentable as an unsigned char or the value of EOF.	In the ASCII character
     set, this includes the following characters (with their numeric values
     shown in octal):

     040 sp	   041 ``!''	 042 ``"''     043 ``#''     044 ``$''
     045 ``%''	   046 ``&''	 047 ``'''     050 ``(''     051 ``)''
     052 ``*''	   053 ``+''	 054 ``,''     055 ``-''     056 ``.''
