Passing parameter in worker thread

[learningvisualc]

Hi all, I have made a worker thread. I want to pass a integer as a parameter in my thread. I am not getting how to do it. Can anybody help me this. Thanks in advance

A thread accepts a void pointer as its parameter. If you want to pass an integer, you first typecast it as a void pointer and then typecast it back to an integer inside the thread function.

can you please explain me using a example.

Thread creation may look like this -

CreateThread(0, 0, Start, (LPVOID)1024, 0, 0);

Here 1024 is the value passed as parameter. The thread function may look like this-

DWORD WINAPI Start(LPVOID p)
{
int i = (int)p;
return 0;
}

Here the passed in parameter will be available in the variable i.
