GetWindowThreadProcessId info Overview Group

The GetWindowThreadProcessId function retrieves the identifier of the thread that created the specified window and, optionally, the identifier of the process that created the window.

DWORD GetWindowThreadProcessId(

HWND hWnd,	// handle of window
LPDWORD lpdwProcessId	// address of variable for process identifier
);

Parameters
