Question

I have the following class:

class A
{
    private:
        int starter()
        {
             //TO_DO: pthread_create()
        }

        void* threadStartRoutine( void *pThis );
}

I want to create a thread from inside starter() to run threadStartRoutine(). I get compile time errors with regard to the third argument, which should take the address of the start routine.

What would be the correct way to call pthread_create() to create a new thread that starts executing threadStartRoutine() ?

I have come across articles online that say that most compilers do not allow non-static member functions to be invoked using pthread_create(). Is this true? What is the reason behind this?

I am compiling my program on Linux-x64 using G++.

Declare the threadStartRountine() as static:

static void* threadStartRoutine( void *pThis );

Otherwise, the type of threadStartRoutine() is:

void* (A::*)(void*)

which is not the type of function pointer that pthread_create() requires.
