- The following line indicates me that the pbuf will be placed in RAM
tcp_pbuf_prealloc(layer, length, mx, os, pcb, api, fst)
pbuf_alloc((layer), (length), PBUF_RAM)
Just to add to Simon's post: please be aware that PBUF_RAM allocations
never draw from the PBUF POOL that you've defined above. If you want
that to happen, define a custom pool instead, and (if relevant) avoid
PBUF_POOL allocations in your own code. Otherwise you'll need a heap (ie
MEM_SIZE).
As far as I can tell, although I'd love to be corrected, there is no way
to have a statically sized pool that is used for both PBUF_RAM and
PBUF_POOL allocations.
