When applying the following function , Report the error above . Tossed all afternoon , At first, I thought it was a coding format problem , The final discovery is 64 Bit compiler , The value of the feedback structure is 64 position , Defined long type hFile Will be cut off , Not right .

So will long hfile Change it to

intptr_t hFile 
 perhaps  
long long hFIle
