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

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 .
