ISPRINT(3)		 BSD 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
     (`	').  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''
     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 re-
     turns non-zero if the character tests true.

COMPATIBILITY
     Although isprint()	accepts	arguments outside of the range of the unsigned
     char type in locales with large character sets, this is a 4.4BSD exten-
     sion and the iswprint() function should be	used instead for maximum
     portability.

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

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