WebUse pthread_key_create (3C) to allocate a key that is used to identify thread-specific data in a process. The key is global to all threads in the process. When the thread-specific data is created, all threads initially have the value NULL associated with the key. Call pthread_key_create () once for each key before using the key. Webpthread_exit in glibc/NPTL causes a "forced unwind" that is almost like a C++ exception, but not quite. On Mac OS X, for example, pthread_exit unwinds without calling C++ destructors.
