  43 .Sh SYNOPSIS
  44 .In ctype.h
  45 .Ft int
  46 .Fn isgraph "int c"
  47 .Sh DESCRIPTION
  48 The
  49 .Fn isgraph
  50 function tests for any printing character except space
  51 .Pq Ql "\ "
  52 and other
  53 locale-specific space-like characters.
  54 The value of the argument must be representable as an
  55 .Vt "unsigned char"
  56 or the value of
  57 .Dv EOF .
  58 .Pp
  59 In the ASCII character set, this includes the following characters
  60 (preceded by their numeric values, in octal):
  61 .Pp
  62 .Bl -column \&000_``0''__ \&000_``0''__ \&000_``0''__ \&000_``0''__ \&000_``0''__

  83 .Sh RETURN VALUES
  84 The
  85 .Fn isgraph
  86 function returns zero if the character tests false and
  87 returns non-zero if the character tests true.
  88 .Sh COMPATIBILITY
  89 The
  90 .Bx 4.4
  91 extension of accepting arguments outside of the range of the
  92 .Vt "unsigned char"
  93 type in locales with large character sets is considered obsolete
  94 and may not be supported in future releases.
  95 The
  96 .Fn iswgraph
  97 function should be used instead.

 103 .Sh STANDARDS
 104 The
 105 .Fn isgraph
 106 function conforms to
 107 .St -isoC .
