线程和C ++ [英] pthreads and C++

问题描述

我正在玩C ++和pthreads，到目前为止这么好。我可以访问类成员函数，如果它是静态的，我已经阅读，我可以访问一个普通的类成员函数，如果我传递this作为参数与pthread_create，因为c ++这样做。但我的问题是，我想给一个int函数，我不知道如何使用pthread_create做多个参数。

I am playing with C++ and pthreads and so far so good. I can access a class member function if it's static and I've read that I can access a normal class member functions if I pass "this" as an argument with pthread_create, because c++ does this to, under the hood. But my problem is that I want to give an int to that function, and I don't know how to do multiple arguments with pthread_create.

推荐答案

传递结构指针。

struct Arg {
  MyClass* _this;
  int      another_arg;
};

...

Arg* arg = new Arg;
arg->_this = this;
arg->another_arg = 12;
pthread_create(..., arg);
...
delete arg;
