  _In_   UINT cbSize,
  _In_   LPMOUSEMOVEPOINT lppt,
  _Out_  LPMOUSEMOVEPOINT lpptBuf,
  _In_   int nBufPoints,
  _In_   DWORD resolution
);

FoxPro declaration:

DECLARE INTEGER GetMouseMovePointsEx IN user32;

	STRING @lppt,;
	STRING @lpptBuf,;
	INTEGER nBufPoints,;
	INTEGER resolution

Parameters:

cbSize [in] The size, in bytes, of the MOUSEMOVEPOINT structure.

lppt [in] A pointer to a MOUSEMOVEPOINT structure containing valid mouse coordinates (in screen coordinates). It may also contain a time stamp.

lpptBuf [out] A pointer to a buffer that will receive the points. It should be at least cbSize* nBufPoints in size.
