interrupt_all is not blocking. However, there is currently a bug in interruption on pthreads which means threads can miss interruptions if they get a spurious condition variable wake at the wrong time. Since interruption causes spurious wakes for other threads waiting on the same cv this is particularly a problem for interrupt_all.
Anthony, what is the schedule, if any, for getting a fix for the bug you refer to? The project I am currently working on, in development within a win32 environment, but soon to be ported to a VxWorks/PPC (using pthreads) environment does use interruption facilities. If this will be a problem for us, let's say not fixed up within the next 6 months, then I'll have to utilize alternate schemes. Geoff Shapiro FLIR Systems, Inc.
