ISPRINT(3) BSD Library Functions Manual ISPRINT(3)
NAME
isprint -- printing character test (space character inclusive)
LIBRARY
Standard C Library (libc, -lc)
SYNOPSIS
##include <>
int
isprint(int c);
DESCRIPTION
The isprint() function tests for any printing character including space
(` '). For single C chars locales (see multibyte(3)) the value of the
argument is representable as an unsigned char or the value of EOF. In
the ASCI character set, this includes the following characters (with
their numeric values shown in octal):
040 sp 041 ``!'' 042 ``"'' 043 ``#'' 044 ``$''
045 ``%'' 046 ``&'' 047 ``''' 050 ``('' 051 ``)''
052 ``*'' 053 ``]'' 054 ``,'' 055 ``-'' 056 ``.''
057 ``/'' 060 ``0'' 061 ``1'' 062 ``2'' 063 ``3''
064 ``4'' 065 ``5'' 066 ``6'' 067 ``7'' 070 ``8''
071 ``9'' 072 ``:'' 073 ``;'' 074 ``<'' 075 ``=''
076 ``>'' 077 ``?'' 100 ``@'' 101 ``A'' 102 ``B''
103 ``C'' 104 ``D'' 105 ``E'' 106 ``F'' 107 ``G''
110 ``H'' 111 ``I'' 112 ``J'' 113 ``K'' 114 ``L''
115 ``M'' 116 ``N'' 117 ``O'' 120 ``P'' 121 ``Q''
122 ``R'' 123 ``S'' 124 ``T'' 125 ``U'' 126 ``V''
127 ``W'' 130 ``X'' 131 ``Y'' 132 ``Z'' 133 ``[''
134 ``\'' 135 ``]'' 136 ``^'' 137 ``'' 140 ```''
141 ``a'' 142 ``b'' 143 ``c'' 144 ``d'' 145 ``e''
146 ``f'' 147 ``g'' 150 ``h'' 151 ``i'' 152 ``j''
153 ``k'' 154 ``l'' 155 ``m'' 156 ``n'' 157 ``o''
160 ``p'' 161 ``q'' 162 ``r'' 163 ``s'' 164 ``t''
165 ``u'' 166 ``v'' 167 ``w'' 170 ``x'' 171 ``y''
172 ``z'' 173 ``{'' 174 ``'' 175 ``}'' 176 ``~''
RETURN VALUES
The isprint() function returns zero if the character tests false and
returns non-zero if the character tests true.
COMPATIBILITY
The 4.4BSD extension of accepting arguments outside of the range of the
unsigned char type in locales with large character sets is considered
obsolete and may not be supported in future releases. The iswprint()
function should be used instead.

STANDARDS
The isprint() function conforms to ISO/IEC 9899:1990 (``ISO C90'').
