类成员函数作为pthread_create函数参数 近⽇需要将线程池封装成C++类,类名为Threadpool。在类的成员函数exec_task中调⽤pthread_create去启动线程执⾏例程 thread_rounter。编译之后报错如下:spfs_threadpool.cpp: In member function ‘int Threadpool::exec_task(task*)’:spfs_threadpool.cpp:174: error: ...
pthread_exit(NULL); return NULL; } int main() { pthread_t some_thread; struct arg_struct args; args.arg1 = 5; args.arg2 = 7; if (pthread_create(&some_thread, NULL, &print_the_arguments, (void *)&args) != 0) { printf("Uh-oh!\n"); return -1; } return pthread_join(some...
第一个参数是“返回参数”:这是您获得创建线程的地方。函数本身返回状态/错误指示。
pthread_t pid;private:static void * start_thread(void *arg) //静态成员函数只能访问静态变量或静态函数,通过传递this指针进⾏调⽤ { Thread *ptr = (Thread *)arg;ptr->fpConnectionRunning(); //线程的实体是run } public:int start(){ if(pthread_create(&pid,NULL,start_thread,(void *)this...
SetPositionY(rand()%15+2); while (1) //游戏循环 { //问题在此 pth1 = pthread_create(&threads, NULL, Controller, (void*)Player &player); } //参数该如何调用? system("pause"); return 0; } 3.报错如下 E:\Workspace\C\Game test\problem.cpp: In function 'int main()': E:\...
pthread_create方法第三个参数只能是C函数指针或者类到静态函数指针。 下面记录一下解决方法 1include <stdio.h>2#include <pthread.h>3#include <unistd.h>45classThread{6public:7Thread(intnum =5):_num(num){ }89staticvoid*work(void*args){//静态函数有访问函数, 变量限制, 这里直接传入类指针变量10...
{ int ret = pthread_create(&m_tid_sleep,NULL,sleepFun,this); if(ret != 0) { printf("Create Thread Fail.\n"); return false; } return true; } //.h void* sleepFun(void* arg); 原因:线程方法必须是静态方法,你如果写在类里,不能是成员函数,需要加static ...

(1)线程函数只有一个参数的情况:直接定义一个变量通过应用传给线程函数。 #include<iostream>#include<pthread.h>usingnamespacestd;pthread_t thread;voidfn(void*arg){inti=*(int*)arg;cout<<"i = "<<i<<endl;return((void*)0);}intmain(){interr1;inti=10;err1=pthread_create(&thread,NULL,fn,&...
