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 re-
     turns 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 ob-
     solete and	may not	be supported in	future releases.  The iswgraph() func-
     tion should be used instead.

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

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