basic threading help
I am very new to threading and am having a small problem i just can't find the solution for. I am wanting to print out the values of args.id and args.delay inside the mythread function. however i am getting the error error "C2228: left of '.id' must have class/struct/union".

struct ThreadArgs{
  int id;
  int delay;
}args ;

void main(){
                unsigned __stdcall mythread(void *data);
                unsigned ThreadId;

                int x = 5;
                args.id = 2;
                args.delay = 3;

                HANDLE hThread = (HANDLE)_beginthreadex(NULL, 0, mythread, &args, 0, &ThreadId);
                WaitForSingleObject(hThread, INFINITE);


unsigned __stdcall mythread(void *data)

                ThreadArgs *args = (ThreadArgs *) data;

                cout<<"hello world"<<endl;
                return 0;

Thanks in advance for any help

Re: basic threading help
args is a pointer, so you must use args->id, not args.id.
