Looking at the calls to VOP_CLOSE, there's either a flags variable, or the fmode variable I mentioned before, being passed as the second parameter. I haven't checked where this comes from in all cases, but when vn_closefile gets called, the value of this parameter is fp->f_flag. Similarly, when an open cannot be completed, the value is fmode. In other words, it looks like the flags are already there. _______________________________________________ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "[EMAIL PROTECTED]"
