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.

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.

SEE ALSO
     ctype(3), isalnum_l(3), iswprint(3), ascii(7)

STANDARDS
     The isprint() function conforms to ISO/IEC 9899:1990 (``ISO C90'').
