The DefWindowProc function calls the default window procedure. The default window procedure provides default processing for any window messages that an application does not process. This function ensures that every message is processed. It should be called with the same parameters as those received by the window procedure.
hwnd
Identifies the window that received the message.
uMsg
Specifies the message to be processed.
wParam
Specifies additional message-dependent information.
lParam
Specifies additional message-dependent information.
The return value is the result of the message processing and depends on the message sent.
