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.	 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 oc-
     tal):

     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 re-
     turns non-zero if the character tests true.

COMPATIBILITY
     Although ispunct()	accepts	arguments outside of the range of the unsigned
     char type in locales with large character sets, this is a 4.4BSD exten-
     sion and the iswpunct() function should be	used instead for maximum
     portability.

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

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