  44 .In ctype.h
  45 .Ft int
  46 .Fn isprint "int c"
  47 .Sh DESCRIPTION
  48 The
  49 .Fn isprint
  50 function tests for any printing character, including space
  51 .Pq Ql "\ " .
  52 The value of the argument must be representable as an
  53 .Vt "unsigned char"
  54 or the value of
  55 .Dv EOF .
  56 .Pp
  57 In the ASCII character set, this includes the following characters
  58 (preceded by their numeric values, in octal):
  59 .Pp

  80 .El
  81 .Sh RETURN VALUES
  82 The
  83 .Fn isprint
  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 iswprint
  95 function should be used instead.

 101 .Sh STANDARDS
 102 The
 103 .Fn isprint
 104 function conforms to
 105 .St -isoC .
