![]() The value_ptr is passed to the thread that calls pthread_join() for this thread. The pthread_exit() function is used to terminate the calling thread. The thread also has the option to refuse termination. The terminating thread may also have to perform some cleanup tasks before it terminates. The terminating thread may terminate immediately or defer termination untilĪ logical point in its execution. It may be necessary to terminate that thread. If a thread performs poorly or is no longer needed, to save system resources Thread that monitors the work of other threads. ![]() It may be necessary for one thread to terminate another thread in the same process. If the terminating thread did not make a call to pthread_exit(), then the exit status will be the return value of the function, if it has one otherwise, the exit status is NULL. The pthread_join() returns the exit status passed to the pthread_exit() function called by the terminating thread. When a joinable thread function has completed executing, it returns to the thread calling pthread_join(), for which it is the target thread. Thread synchronization also includes when and how threads are terminated and canceled.Ī thread's execution can be discontinued by several means:īy returning from the execution of its assigned task with or without an exit status or return valueīy explicitly terminating itself and supplying an exit statusīy being canceled by another thread in the same address space This will briefly be discussed in thisĬhapter and fully discussed in Chapter 5. The scheduling, priority, and scope of the thread can be set by using a thread attribute object.īecause threads share resources, access to resources will have to be synchronized. Thread performance is also determined by how the threads compete for resources, either onĪ process or system scope. Part of managing threads is setting the scheduling policy and priority of the threads. ![]() When creating applications with multiple threads, there are several ways to control how threads perform and how threads useĪnd compete for resources.
