available (closefrom() was added to FreeBSD in 8.0-release). The selection is made at compile-time, as I still compile a FreeBSD-based version of lpr&friends on other platforms. While testing I out that (at least on my system) lpd has been closing 11095 fd's, when there are only 6 fd's open. The old code took 120 times more clocktime than calling closefrom(). (although that was still less than 2/1000-ths of a second!) Reviewed by: jilles MFC after: 2 weeks |
