The ThreadProc function is an application-defined function that serves as the starting address for a thread. Specify this address when calling the CreateThread or CreateRemoteThread function. The LPTHREAD_START_ROUTINE type defines a pointer to this callback function. ThreadProc is a placeholder for the application-defined function name.
DWORD WINAPI ThreadProc(
LPVOID lpParameter // thread data
);
The function should return a value that indicates its success or failure.
A process can obtain the return value of the ThreadProc of a thread it created with CreateThread by calling the GetExitCodeThread function. A process cannot obtain the return value from the ThreadProc of a thread it created with CreateRemoteThread.
