ISGRAPH(3)	       FreeBSD Library Functions Manual		    ISGRAPH(3)

NAME
     isgraph --	printing character test	(space character exclusive)

LIBRARY
     Standard C	Library	(libc, -lc)

SYNOPSIS
     #include <ctype.h>

     int
     isgraph(int c);

     int
     isgraph_l(int c, locale_t loc);

DESCRIPTION
     The isgraph() function tests for any printing character except space
     (`	') and other locale-specific space-like	characters.  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):

     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 isgraph_l() function takes an explicit	locale argument, whereas the
     isgraph() function	uses the current global	or per-thread locale.

RETURN VALUES
     The isgraph() and isgraph_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
     obsolete and may not be supported in future releases.  The	iswgraph()
     function should be	used instead.

SEE ALSO
     ctype(3), iswgraph(3), ascii(7)

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