Error: (pointer to array) may not be used in a subscript operation. How could I solve it?

Hello everybody.

I have a pointer like this:

float **p = ...;
...
#pragma offload target(mic) in(p[0]:length(...))
_FUNCITON_

Then I got error info: ` "p" may not be used in a subscript operation.` when compiling it.

So how could I pass a one-dimensional array like this to mic? any advice and suggestions will be greatly appreciated!
