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.  For single C
     chars locales (see multibyte(3)) the value of the argument is repre-
     sentable 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''

     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.

STANDARDS

     The isgraph() function conforms to ISO/IEC 9899:1990 (``ISO C90'').
