Matlab Coder generated C/mex shallow copy

I'm new to using MatLab Coder and am playing around with it to create MEX and C files. I currently have a simple function which swaps two variables i and f (which will be structs each containing an int16 array):

function [i,f] = structSwap(i,f) %#codegen
    temp = f;
    f = i;
    i = temp;
end

I would like to have it so that the generated C code does a shallow copy by simply swapping the pointers to each struct. However, I cannot seem to find a way to do so - it looks like the code always comes out as a deep copy:

void structSwap(const emlrtStack *sp, struct0_T *i, struct0_T *f)
{
  struct0_T temp;
  emlrtHeapReferenceStackEnterFcnR2012b(sp);
  emxInitStruct_struct0_T(sp, &temp, &b_emlrtRTEI, true);
  emxCopyStruct_struct0_T(sp, &temp, f, &b_emlrtRTEI);
  emxCopyStruct_struct0_T(sp, f, i, &c_emlrtRTEI);
  emxCopyStruct_struct0_T(sp, i, &temp, &d_emlrtRTEI);
  emxFreeStruct_struct0_T(&temp);
  emlrtHeapReferenceStackLeaveFcnR2012b(sp);
}

static void emxCopy_int16_T(const emlrtStack *sp, emxArray_int16_T **dst,
  emxArray_int16_T * const *src, const emlrtRTEInfo *srcLocation)
{
  int32_T numElDst;
  int32_T numElSrc;
  int32_T i;
  numElDst = 1;
numElSrc = 1;
for (i = 0; i < (*dst)->numDimensions; i++) {
  numElDst *= (*dst)->size[i];
  numElSrc *= (*src)->size[i];
}

for (i = 0; i < (*dst)->numDimensions; i++) {
  (*dst)->size[i] = (*src)->size[i];

      }

      emxEnsureCapacity(sp, (emxArray__common *)*dst, numElDst, (int32_T)sizeof
                        (int16_T), srcLocation);
      for (i = 0; i < numElSrc; i++) {
        (*dst)->data[i] = (*src)->data[i];
      }
    }

Is there any option or method which I can use to make the coder perform a shallow copy instead by simply swapping the references?
