// ISPRINT(3)                 Library Functions Manual                ISPRINT(3)
//
// 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
//      (‘ ’).  The value of the argument must be representable as an unsigned
//      char or the value of EOF.
//
//      In the ASCII character set, this includes the following characters
//      (preceded by their numeric values, in octal):
//
//      040  sp   041 ``!'' 042 ``"'' 043 ``#'' 044 ``$''
//      045 ``%'' 046 ``&'' 047 ``''' 050 ``('' 051 ``)''
//      052 ``*'' 053 ``+'' 054 ``,'' 055 ``-'' 056 ``.''
//      057 ``/'' 060 ``0'' 061 ``1'' 062 ``2'' 063 ``3''
//      064 ``4'' 065 ``5'' 066 ``6'' 067 ``7'' 070 ``8''
//      071 ``9'' 072 ``:'' 073 ``;'' 074 ``<'' 075 ``=''
//      076 ``>'' 077 ``?'' 100 ``@'' 101 ``A'' 102 ``B''
//      103 ``C'' 104 ``D'' 105 ``E'' 106 ``F'' 107 ``G''
//      110 ``H'' 111 ``I'' 112 ``J'' 113 ``K'' 114 ``L''
//      115 ``M'' 116 ``N'' 117 ``O'' 120 ``P'' 121 ``Q''
//      122 ``R'' 123 ``S'' 124 ``T'' 125 ``U'' 126 ``V''
//      127 ``W'' 130 ``X'' 131 ``Y'' 132 ``Z'' 133 ``[''
//      134 ``\'' 135 ``]'' 136 ``^'' 137 ``_'' 140 ```''
//      141 ``a'' 142 ``b'' 143 ``c'' 144 ``d'' 145 ``e''
//      146 ``f'' 147 ``g'' 150 ``h'' 151 ``i'' 152 ``j''
//      153 ``k'' 154 ``l'' 155 ``m'' 156 ``n'' 157 ``o''
//      160 ``p'' 161 ``q'' 162 ``r'' 163 ``s'' 164 ``t''
//      165 ``u'' 166 ``v'' 167 ``w'' 170 ``x'' 171 ``y''
//      172 ``z'' 173 ``{'' 174 ``|'' 175 ``}'' 176 ``~''
//
// RETURN VALUES
//      The isprint() function returns zero if the character tests false and
//      returns non-zero if the character tests true.
