ISGRAPH(3)		 BSD 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);

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 ``~''

RETURN VALUES
     The isgraph() 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 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”).
