为了避免存储器泄漏,每个可结合线程都应该要么被显示地回收,即调用pthread_join;要么通过调用pthread_detach函数被分离。 [cpp] int pthread_join(pthread_t tid, void**thread_return); 若成功则返回0,若出错则为非零。 int pthread_join(pthread_t tid, void**thread_return); 若成功则返回0,若出错则为非零...
#define _UNIX03_THREADS #include <pthread.h> int pthread_detach(pthread_t thread); General description Allows storage for the thread whose thread ID is in the location thread to be reclaimed when that thread ends. This storage is reclaimed on process exit, regardless of whether the thread was...
pthread_detach(threadid)和pthread_detach(pthread_self())的区别应该是调用他们的线程不同,没其他区别。 pthread_detach(threadid) 函数的功能是使线程ID为threadid的线程处于分离状态,一旦线程处于分离状态,该线程终止时底层资源立即被回收;否则终止子线程的状态会一直保存 (占用系统资源)直到主线程调用pthread_join(...
pthread_t id1,id2; void *a1,*a2; int i,ret1,ret2; char s1[]="This is first thread!"; char s2[]="This is second thread!"; ret1=pthread_create(&id1,NULL,(void *) thread1,s1); ret2=pthread_create(&id2,NULL,(void *) thread2,s2); if(ret1!=0){ printf ("Create pthrea...

pthread_detach(pthread_self()) 或者父线程调用 pthread_detach(thread_id)(非阻塞,可立即返回) 这将该子线程的状态设置为detached,则该线程运行结束后会自动释放所有资源。
pthread_t thread_id; while( 1 ) { pthread_create( &thread_id, NULL, (void *)print_message, (void *)NULL );//一个线程默认的状态是joinable } return 0; } void print_message( void *ptr ) { pthread_detach(pthread_self());//pthread_detach(pthread_self()),将状态改为unjoinable状态,...
0不会调用。 } int main(int argc,char *argv[]) { pthread_t thread_id; //存放线程的标识符 /*1. 创建线程*/ if(pthread_create(&thread_id,NULL,start_routine,NULL)!=0) { printf("线程创建失败!\n"); } /*2.设置线程的分离属性*/ if(pthread_detach(thread_id)!=0) { printf("分离...
pthread_detach(threadId); } // 后台线程调用函数 void *demo(void *params) { NSString *str = (__bridge NSString *)(params); NSLog(@"%@ - %@", [NSThread currentThread], str); return NULL; } 小结 在c语言中,没有对象的概念,对象类型是以-t/Ref结尾的,并且声明的似乎不需要用*。
