WHat is a reentrant function?

I have seen in many programmes the following code :

foo(int *iptr)
{
        int     j;

        j = ptr;
}

ok, forget the cast for now, this is slightly tricky if sizeof(int) !=
sizeof(*) on some architectures.

fine. but why doesn't the guy just say int *iptr2 = iptr1 in the above
code.

Is it a performance eenhancement to equate it to int rahter then a pointr
in th e fucnntion ?

Mind you, he uses it as a pointer(i.e. j) in the code after the
assignment.
