ThreadProc

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
);
 

Parameters

lpParameter

Receives the thread data passed to the function using the lpParameter parameter of the CreateThread or CreateRemoteThread function.

Return Values

The function should return a value that indicates its success or failure.

Remarks

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.
