After the unified buffer cache modifications happen in the NetBSD kernel, the difference will be much less noticeable. : Now, I am having a problem though. I cannot figure out how to implement : -w and -x. For -x, I tried modifying the regular expression (foo) into : ^(foo)$ before compiling, but that did not work. I intended to do : something similar with -w. Anyway, I am probably missing the obvious, but : does anyone have any ideas regarding how I should implement -w and -x? Hm. Adding ^ and $ should work, provided you don't specify either REG_NOTBOL or REG_NOTEOL. (I assume that (foo) above, including the parens, is the RE. With the parens, it depends whether you're using standard REs or extended REs. :) Thatnks for this work ... I'll leave it to another soul to do something with it in NetBSD. -- -- Todd Vierling (t...@pobox.com) To Unsubscribe: send mail to majord...@freebsd.org with "unsubscribe freebsd-hackers" in the body of the message
