Retrieves a handle to the window (if any) that has captured the mouse. Only one window at a time can capture the mouse; this window receives mouse input whether or not the cursor is within its borders.
This function has no parameters.
The return value is a handle to the capture window associated with the current thread. If no window in the thread has captured the mouse, the return value is NULL.
A NULL return value means the current thread has not captured the mouse. However, it is possible that another thread or process has captured the mouse.
To get a handle to the capture window on another thread, use the GetGUIThreadInfo function.
