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
     The 4.4BSD	extension of accepting arguments outside of the	range of the
     unsigned char type	in locales with	large character	sets is	considered ob-
     solete and	may not	be supported in	future releases.  The iswpunct() func-
     tion should be used instead.

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

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