Thanks Jifl

yesterday night i found the same solution... i saw pbuf_copy() function in lwip code.
If my idea works, i will post a message about it.

The caller needs to duplicate it? That's fine. Just allocate another pbuf
of size p->tot_len. Depending where this is happening, it may want to be
PBUF_POOL or PBUF_RAM. Probably PBUF_POOL.

Then call pbuf_copy which is defined in pbuf.h:
err_t pbuf_copy(struct pbuf *p_to, struct pbuf *p_from);
