I've recently started using Boost and am working with 1.28.0 (modified to include the latest Boost.Signals from the CVS repository). I just obtained David Moore's thread_pool implementation from http://groups.yahoo.com/group/boost/files/thread_pool.zip and tweaked it slightly in order to build it with gcc 2.95.3 (no <limits>). I since noticed some more recent thread_pool source on CVS under boost/boost/libs/thread/src/Attic (bill_kempf). What is the purpose of the Attic subdirs? - unofficial work-in-progress type stuff or would I be better off using these versions of thread_pool? Also, is thread_pool likely to be included in the next official Boost release? Any idea when this might be? Finally, is a boost::xtime replacement likely to appear in the next release? Thanks for your assistance, Niall (Boost newbie) --------------------------------- SOLD.com.au- Find yourself a bargain! [Non-text portions of this message have been removed]
