(We do define NULL to be a zero-with-cast, but programs should not assume that NULL will be of pointer type -- "An integer constant expression with the value 0, or such an expression cast to type void *, is called a null pointer constant".) -Ben _______________________________________________ svn-src-all@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/svn-src-all To unsubscribe, send any mail to "svn-src-all-unsubscr...@freebsd.org"
