Assuming the program is built with that definition set, yes 64-bit offsets are used on a 32-bit machine. I've rebuilt a number of apps (apache, vsftpd, etc.) so they don't choke on huge log files. Unfortunately, a number of utilities are still built "wrongly" (2G file size maximum and the use of signed integers for offsets instead of "off_t"), so be warned. ---------------------------------------------------------------------- - Rick Stevens, Senior Systems Engineer rstevens@xxxxxxxxxxxxxxx - - VitalStream, Inc. http://www.vitalstream.com - - - - Warning: You are logged into reality as the root user... - ----------------------------------------------------------------------
