OpenClipboard function (winuser.h)
Opens the clipboard for examination and prevents other applications from modifying the clipboard content.
BOOL OpenClipboard( HWND hWndNewOwner );
A handle to the window to be associated with the open clipboard. If this parameter is NULL, the open clipboard is associated with the current task.
If the function succeeds, the return value is nonzero.
If the function fails, the return value is zero. To get extended error information, call GetLastError.
OpenClipboard fails if another window has the clipboard open.
An application should call the CloseClipboard function after every successful call to OpenClipboard.
The window identified by the hWndNewOwner parameter does not become the clipboard owner unless the EmptyClipboard function is called.
For an example, see Copying Information to the Clipboard.
