Hi,
You should not add any members to anything inside the LwIP. Treat it as a close
black box with interface.
If you need any parameters this should be defined inside your own code. The
simplest will be defining your
own structure and when you get a new connection you assigne it to the new PCB.
Example:
------------------------------------------------------------------------------------------------------
// Allocate memory for the structure that holds the local variables related
// to the new connection
ts = (__tcp_term_ts*)mem_malloc(sizeof(__tcp_term_ts));
// Tell TCP that this is the structure we wish to be passed for our
callbacks.
tcp_arg(pcb, ts);
------------------------------------------------------------------------------------------------------
In the above example __tcp_term_ts is your own definition. Every call back
function gives you a pointer to
This param.
Hope this helped,
Noam.

Subject: [lwip-users] Can I add some members to struct pbuf?
I want to add some members to struct pbuf. Then, it caused assertions
like this:
pbuf_free: p->ref > 0 mem_free: mem->usedpbuf_free:p->ref > 0
infinitely.
why does this happen?
