ISPRINT(3)            DragonFly Library Functions Manual            ISPRINT(3)


NAME

     isprint, isprint_l -- printing character test (space character inclusive)


LIBRARY

     Standard C Library (libc, -lc)


SYNOPSIS

     #include <ctype.h>

     int
     isprint(int c);

     int
     isprint_l(int c, locale_t locale);


DESCRIPTION

     The isprint() and isprint_l() functions test 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 (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 ``~''

     The _l-suffixed version takes an explicit locale argument, whereas the
     non-suffixed version uses the current global or per-thread locale.


RETURN VALUES

     The isprint() and isprint_l() functions return 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() and
     iswprint_l() functions should be used instead.


SEE ALSO

     ctype(3), ctype_l(3), iswprint(3), iswprint_l(3), xlocale(3), ascii(7)


STANDARDS

     The isprint() function conforms to ISO/IEC 9899:1990 (``ISO C90'').  The
     isprint_l() function conforms to IEEE Std 1003.1-2008 (``POSIX.1'').
