I understood the porting issue. But still I am not able to get the 
complete idea behind this void. So my foolish Qs are :

The sizeof(FILE) is 148 & sizeof(void) is 1. Does it mean anything ?
and System dependent lib only can process the file descriptor ?

I try to pass a void ptr to the ftell(), then I got the compilation
error "invalid use of void expression".  With out casting, How it 
found that, ptr is NOT a type FILE ?
