Go through a pbuf chain and replace any PBUF_REF buffers with PBUF_POOL (or PBUF_RAM) pbufs, each taking a copy of the referenced data. Note: You MUST explicitly use p = pbuf_take(p); The pbuf you give as argument, may have been replaced by pbuf_take()! Splet14. jan. 2004 · Create PBUF_POOL (or PBUF_RAM) copies of PBUF_REF pbufs.

If the pbuf gets queued, then pbuf_take should be called to copy the buffer.
