Hi,
I don't see any reason to change the UDF
The following script work fine

#include <Memory.au3>
#include <Misc.au3>
#include <Clipboard.au3>
#include <MsgBoxConstants.au3>
#include <WinAPIConv.au3>

Local $sFilePath = '<path to your file>|other file'
_ClipPutFile($sFilePath)
MsgBox($MB_SYSTEMMODAL, "_ClipPutFile()", "Content of Clipboard:" & @CRLF & ClipGet())

The function _ClipPutFile() uses SetClipboardData. MSDN state that if SetClipboardData succeeds, the system owns the object identified by the hMem parameter. The application may not write to or free the data once ownership has been transferred to the system, but it can lock and read from the data until the CloseClipboard function is called.
