ispunct

punctuation character test
Standard C Library (libc, -lc)
#include
<ctype.h>
int
ispunct
(int
c);
The
ispunct
()
function tests for any printing character, except for space
(‘
’) or a character for which
isalnum(3) is true. 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 (preceded by their numeric values, in octal):
041 ``!'' 042 ``"'' 043 ``#'' 044 ``$'' 045 ``%'' |
046 ``&'' 047 ``''' 050 ``('' 051 ``)'' 052 ``*'' |
053 ``+'' 054 ``,'' 055 ``-'' 056 ``.'' 057 ``/'' |
072 ``:'' 073 ``;'' 074 ``<'' 075 ``='' 076 ``>'' |
077 ``?'' 100 ``@'' 133 ``['' 134 ``\'' 135 ``]'' |
136 ``^'' 137 ``_'' 140 ```'' 173 ``{'' 174 ``|'' |
175 ``}'' 176 ``~'' |
The ispunct
() function returns zero if the
character tests false and returns non-zero if the character tests true.
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 iswpunct
()
function should be used instead.
The ispunct
() function conforms to
ISO/IEC 9899:1990
(“ISO C90”).
