join.c文件一共有三个函数,下面我们一个个看一下。 1 pthread_exit // 线程退出 void pthread_exit(void * retval) { // 获取当前线程的结构体 pthread_t self = thread_self(); pthread_t joining; struct pthre…
int thrd_join(thrd_t thr, int *result); 调用thread_join()的线程会被阻塞,直到通过 thr 标识的线程执行完成,这里“阻塞”(block)指的是:线程会在调用 thread_join()的位置停留必要的时间。然后,thread_join()将线程 thr 中执行函数的返回值写入指针 result 所引用的 int 变量中,假设 result 不是一个空...
status=pthread_create(&threads[i], NULL, ptintf_hello_world, &i); if(status != 0){//线程创建不成功,打印错误信息 printf("pthread_create returned error code %d\n", status); exit(-1); } } for(i=0; i < NUMBER_OF_THREADS; i++){ pthread_join(threads[i], NULL); } exit(0); ...

int numthreads; void join_threads(void) { cnode *curnode; printf("joining threads...\n"); while (numthreads) { pthread_mutex_lock(&cq.control.mutex); /* below, we sleep until there really is a new cleanup node. This takes care of any false wakeups... even if we break out of ...
pthread_join ( producerThread[ index ], NULL ); // unsuccessful if ( closed != 0 ) { fprintf ( stderr, "Thread failed to close." ); exit ( 3 ); } }// end of join producer threads }// end of close threads 我应该让两个线程数组将每个线程与主线程连接起来,但这并没有发生,控制台...
cpthread_join;编译并链接：编译时需要链接pthread库。在gcc中，可以通过添加pthread选项来实现。bashgcc pthread o my_program my_program.c示例代码：c#include <pthread.h>#include <stdio.h>#include <stdlib.h>#include <unistd.h>void* thread_function {int* num = arg;printf;sleep; // ...
pthread_join(pool->threads[i], NULL); } // 释放线程池资源 free(pool->threads); free(pool->queue); pthread_mutex_destroy(&pool->lock); pthread_cond_destroy(&pool->not_empty); pthread_cond_destroy(&pool->not_full); } ```
等待线程终止pthread_join会堵塞调用线程,直到其指定的线程终止。pthread_join通过第一个參数:线程ID来指定线程。调用者调用pthread_jion等待一个特定线程终止,在这样的情况下,调用者可能须要这个特定线程的返回值,pthread_join通过将value_ptr的地址赋值给特定线程的pthread_exit的ret获取返回值。
