ISPUNCT(3)		 BSD Library Functions Manual		    ISPUNCT(3)

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 (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 ``~''

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), iswpunct(3), ascii(7)

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