Not portably, if you are unwilling to use lsof. We will probably break you every release and potentially every SU. Hope you are OK with that, since you are using undocumented and unsupported SPI by using that sysctl. If you need to know what it packs in the buffer by default on 10.4.7, it's a struct filelist followed by N struct extern_file's. Your best bet when you have questions like these is to look at the xnu sources for the OS version you are interested in, since, as I implied, this can change from version to version of the OS. Unless your constraint is specifically "don't popen lsof", I would recommend using lsof. -- Terry _______________________________________________ Do not post admin requests to the list.
