ISPUNCT(3)	      DragonFly 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.  For single C chars
     locales the value of the argument is representable as an unsigned char or
     the value of EOF.	In the ASCII character set, this includes the follow-
     ing 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.
