digitalmars.D.learn - Attach and detach C threads to D runtime

Hi, I am currently writing a fuse wrapper for D and try to support fuse multithreading which is based on pthreads. However fuse doesn't offer me a proper way to hook into the creation and joining process of threads. I can attach the threads created by libfuse but cannot find a way to properly detach the threads from the runtime: My current approach: Whenever a fuse function is called I check with a thread local variable "isAttached" if the current thread is already attached, if not, I call thread_attachThis. This works fine and let the GC properly suspend the threads, however when fuse_main() returns all threads are gone but the Druntime still tracks the now non-existant threads anymore. When the GC does a final sweep it will crash. Any ideas how to unregister my threads beforehand. I know that thread_detachByAddr exists, but the Thread object from Thread.getAll or Thread.opApply doesn't expose the thread address. Hints? - Thanks,David

Alternately, you can use pthread_self to get the current thread's address on Posix and GetCurrentThreadId on Windows.
