WebThe pthread_getschedparam () function returns the scheduling policy and parameters of the thread thread, in the buffers pointed to by policy and param, respectively. The returned priority value is that set by the most recent pthread_setschedparam (), pthread_setschedprio (3), or pthread_create (3) call that affected thread. Webpthread_detach() (Detach Thread) indicates that system resources for the specified thread should be reclaimed when the thread ends. pthread_equal() (Compare Two Threads) compares two Pthread handles for equality. pthread_exit() (Terminate Calling Thread) terminates the calling thread, making its exit status available to any waiting threads.
