[lwip-users] Pbuf Copy to Another Pbuf

[Duygu D.]

Hello,

I need to copy pBuf to another pBuf member, and I need to change size of the new buffer to be 1 larger than the previous one.

I am doing like these,

  mpBuf = pbuf_alloc(PBUF_RAW, p->len + (p->next? p->next->tot_len: 0) + 1, PBUF_POOL);

  mpBuf->len = p->len + 1;

  mpBuf->tot_len = mpBuf->tot_len + 1;

  for(i = 0; i < (p->len) ; i++)

  {

  ((uint8_t*)mpBuf->payload)[dummyCounter] = ((uint8_t*)p->payload)[dummyCounter];

  }

But I couldnt sure, successfully copied. What is the correct way ?
