+FUNCTION
+<<ispunct>>---punctuation character predicate
+
+INDEX
+ispunct
+
+ANSI_SYNOPSIS
+#include <ctype.h>
+int ispunct(int <[c]>);
+
+TRAD_SYNOPSIS
+#include <ctype.h>
+int ispunct(<[c]>);
+
+DESCRIPTION
+<<ispunct>> is a macro which classifies ASCII integer values by table
+lookup.  It is a predicate returning non-zero for printable
+punctuation characters, and 0 for other characters.  It is defined
+only when <<isascii>>(<[c]>) is true or <[c]> is EOF.
+
+You can use a compiled subroutine instead of the macro definition by
+undefining the macro using `<<#undef ispunct>>'.
+
+RETURNS
+<<ispunct>> returns non-zero if <[c]> is a printable punctuation character 
+(<<isgraph(<[c]>) && !isalnum(<[c]>)>>).
+
+PORTABILITY
+<<ispunct>> is ANSI C.
+
+No supporting OS subroutines are required.
