ISGRAPH(3) FreeBSD Library Functions Manual ISGRAPH(3)
NAME
isgraph, isgraph_l - printing character test (space character exclusive)
LIBRARY
Standard C Library (libc, -lc)
SYNOPSIS
#include <ctype.h>
int
isgraph(int c);
int
isgraph_l(int c, locale_t loc);
DESCRIPTION
The isgraph() and isgraph_l() functions test for any printing character
except space (` ') and other locale-specific space-like characters. The
value of the argument must be representable as an unsigned char or the
value of EOF.
In the ASCII character set, this includes the following characters (with
their numeric values shown in octal):
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 ``~''
The isgraph_l() function takes an explicit locale argument, whereas the
isgraph() function uses the current global or per-thread locale.
RETURN VALUES
The isgraph() and isgraph_l() functions return zero if the character
tests false and return 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 iswgraph() or
iswgraph_l() function should be used instead.
