From the Delphi FAQ:
Question:
Where is the Windows API function CopyCursor defined in
32-Bit versions of Delphi and C++ Builder?
Answer:
While the call is documented in the Win32 help file, the
function is simply mapped to the Windows API function
CopyIcon(). Note that the 32 bit version of CopyIcon
does not take a hInstance parameter.
