#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. 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 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 ``/''
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'').
