Question

// Here I want to attach a thread to a member function of class

How can I pass t

Answer 1

You need to create a free extern "C" function as a trampoline:

class foo
{
public:
    void *thread_func();
};

extern "C" void *thread_func(void *arg)
{
    return static_cast(arg)->thread_func();
}

foo f;
pthread_create(..., thread_func, &f);
