SYNOPSIS

DESCRIPTION

   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.
