NAME
     ispunct -- punctuation character test

LIBRARY
     Standard C Library (libc, -lc)

SYNOPSIS
     #include <ctype.h>

     int
     ispunct(int c);

DESCRIPTION
     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 ``~''

RETURN VALUES
     The ispunct() 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 iswpunct() function should be used instead.

SEE ALSO
     ctype(3), isalnum_l(3), iswpunct(3), ascii(7)

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