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

  93 .Sh STANDARDS
  94 The
  95 .Fn ispunct
  96 function conforms to
  97 .St -isoC .
