C++ using a member function of a class to pass parameters to a thread
To pass parameters to a thread using a member function of a class in C++, you can follow these steps:
Define a class that contains the member function you want to execute in the thread. Let's call this class "MyClass". The member function should have the desired parameters as its arguments.
Create an instance of the class "MyClass". Let's call this instance "myObject".
Use the
std::thread
class from the C++ Standard Library to create a thread and execute the member function. Pass the member function as the first argument to thestd::thread
constructor, and provide the arguments for the member function as the subsequent arguments.
Example:
std::thread myThread(&MyClass::myMemberFunction, myObject, arg1, arg2);
In the example above, &MyClass::myMemberFunction
is the member function pointer, myObject
is the instance of the class, and arg1
and arg2
are the arguments for the member function.
- You can then call the
join()
member function on thestd::thread
object to wait for the thread to finish its execution.
Example:
myThread.join();
This will ensure that the main thread waits for the newly created thread to complete its execution before continuing.
By following these steps, you can use a member function of a class to pass parameters to a thread in C++.
