Mutex with PTHREAD in Windows?

Question

当线程调用pthread_exit（NULL）终止其执行时，其互斥锁是否可用？

Answer 1

From the documentation of pthread_exit :

The pthread_exit() function shall terminate the calling thread and make the value value_ptr available to any successful join with the terminating thread. Any cancellation cleanup handlers that have been pushed and not yet popped shall be popped in the reverse order that they were pushed and then executed. After all cancellation cleanup handlers have been executed, if the thread has any thread-specific data, appropriate destructor functions shall be called in an unspecified order. Thread termination does not release any application visible process resources, including, but not limited to, mutexes and file descriptors, nor does it perform any process-level cleanup actions, including, but not limited to, calling any atexit() routines that may exist.

So no, your mutex will not be released.
