实时调度与线程编程深入解析

1. 实时调度代码示例

以下是一段实时调度相关的代码：

60 exit (0); 61 > 62 #endif 63 errno_abort ("Get SCHED_RR min priority"); 64 > 65 for (count = 0; count < THREADS; count++) { 66 threads[count].index = count; 67 status = pthread_create ( 68 ^threads[count].id, NULL, 69 thread_routine, (void*)sthreads[count]); 70 if (status != 0) 71 err_abort (status, "Create thread"); 72 > 73 for (count = 0; count < THREADS; count++) { 74 status = pthread_join (threads[count].id, NULL); 75 if (status !=0) 76 err_abort (status, "Join thread;) ״ 77 } 78 printf ("Main exiting\n"); 79 return 0; 80 }

这段代码主要完成了线程的创建和等待线程结束的操作。具体步骤如下：
1. 通过pthread_create函数创建多个线程，每个线程的索引被赋值，并且指定了线程的执行函
