如何將成員函數作爲參數傳遞給pthread_create函數？

實施例：

class A 
    { 
     public: 
     A(){} 

     void funcForThread(Person p) { 
      //code... 
     } 

     void createThread(Person p) { 
      pthread_t thread1; 
      pthread_attr_init (&attr); 
      pthread_attr_setdetachstate (&attr, PTHREAD_CREATE_JOINABLE); 
      pthread_create (&thread1, &attr, /* what to write here*/); // need to pass funcForThread and Person p object there 
     } 

     private: 
     pthread_attr_t attr; 
    };

就這樣

void * 
call_member(void *data) 
{ 
    A *a = reinterpret_cast<A *>(data); 
    a->member(); 

    return NULL; 
} 

然後，

pthread_create(&thread1, &attr, call_member, this);
