SYNOPSIS

     #include <ctype.h>

     int
     isprint(int c);

DESCRIPTION

     The isprint() function tests for any printing character including space
     (` ').  For single C chars locales (see multibyte(3)) the value of the
     argument is representable 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 ``.''
     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''

     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.

COMPATIBILITY

     The 4.4BSD extension of accepting arguments outside of the range of the
     unsigned char type in locales with large character sets is considered
     obsolete and may not be supported in future releases.  The iswprint()
     function should be used instead.
