Ok, so how do i use _beginthread() inside a class without having to make the function i want the thread to use static, also the function that i wanna use for the thread is in the class. Its like this:


class SaidClass {
public:

void INIT();
void saidthread(void* parm);
};

void SaidClass::INIT()
{
_beginthread(saidthread,0,NULL);
}

void SaidClass:saidthread(void* parm);
{
printf("Said Class is working! \n");
}

Thanks

You can't pass a pointer to member function to _beginthread(). However, what you can do is pass a pointer to a static member function that uses the void * data you give to _beginthread() to call a normal member function. Ex:

class SaidClass {  public:    void INIT();    void saidthread(void);        static void thunk(void * ptr) {      reinterpret_cast<SaidClass *>(ptr)->saidthread();    }};void SaidClass::INIT() {  _beginthread(&SaidClass::thunk,0,this);}void SaidClass::saidthread(void) {  printf("Said Class is working! \n");}
