  47 .Sh SYNOPSIS
  48 .In ctype.h
  49 .Ft int
  50 .Fn ispunct "int c"
  51 .Sh DESCRIPTION
  52 The
  53 .Fn ispunct
  54 function tests for any printing character, except for space
  55 .Pq Ql "\ "
  56 or a
  57 character for which
  58 .Xr isalnum 3
  59 is true.
  60 For single C
  61 .Va char Ns s
  62 locales (see
  63 .Xr multibyte 3 ) ,
  64 the value of the argument is
  65 representable as an
  66 .Li unsigned char
  67 or the value of
  68 .Dv EOF .
  69 In the ASCII character set, this includes the following characters
  70 (preceded by their numeric values, in octal):
  71 .Pp
  72 .Bl -column \&000_``0''__ \&000_``0''__ \&000_``0''__ \&000_``0''__ \&000_``0''__
  73 .It "\&041\ ``!'' \t042\ ``""'' \t043\ ``#'' \t044\ ``$'' \t045\ ``%''"
  74 .It "\&046\ ``&'' \t047\ ``''' \t050\ ``('' \t051\ ``)'' \t052\ ``*''"
  75 .It "\&053\ ``+'' \t054\ ``,'' \t055\ ``-'' \t056\ ``.'' \t057\ ``/''"
  76 .It "\&072\ ``:'' \t073\ ``;'' \t074\ ``<'' \t075\ ``='' \t076\ ``>''"
  77 .It "\&077\ ``?'' \t100\ ``@'' \t133\ ``['' \t134\ ``\e\|'' \t135\ ``]''"
  78 .It "\&136\ ``^'' \t137\ ``_'' \t140\ ```'' \t173\ ``{'' \t174\ ``|''"
  79 .It "\&175\ ``}'' \t176\ ``~''"
  80 .El
  81 .Sh RETURN VALUES
  82 The
  83 .Fn ispunct
  84 function returns zero if the character tests false and
  85 returns non-zero if the character tests true.
  86 .Sh COMPATIBILITY
  87 The
  88 .Bx 4.4
  89 extension of accepting arguments outside of the range of the
  90 .Vt "unsigned char"
  91 type in locales with large character sets is considered obsolete
  92 and may not be supported in future releases.
  93 The
  94 .Fn iswpunct
  95 function should be used instead.

 105 function conforms to
