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.
     For single C chars locales the value of the argument is 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''

     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''

     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 ``~''
