ISPRINT(3)		     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 loc);

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 isprint_l() function takes an explicit locale argument, whereas the is-
     print() function uses the current global or per-thread locale.

RETURN VALUES
     The isprint() and isprint_l() functions return zero if the character  tests
     false and return 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 obso-
     lete and may not be supported in future releases.	The iswprint()	or  isw-
     print_l() function 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").

HISTORY
     The isprint() function first appeared in Version 7 AT&T UNIX.
