If it's actually an application, and you can target 10.6, use -[NSRunningApplication executableArchitecture]. Otherwise, you can use sysctl() as illustrated in this Tech Q&A <http://developer.apple.com/library/mac/#qa/qa2001/qa1123.html>. Somewhere in the kinfo_proc is the flag you're looking for. This came up previously on Apple's mailing lists, so search the archives.
