[lwip-users] Re: [lwip] DHCP clean reinitialization?

[Leon Woestenberg]

Hello Scott,

I have never thought that to be a (hidden) feature of lwIP, so no this
was not an issue on the to-do list (yet!).

Are you sure that calling the init()s will free all allocated resources
that are allocated when you start a re-init?

Hmm, when I think of it, yes, this seems to be true, as all mem*_init()
forget every memory resource previously allocated so the modules
themselves can just "forget" any references without properly free()ing
them.

Is this intentional? Maybe Adam knows?

I will patch DHCP so that it initializes the list to NULL on init(). It
won't break
anything. Thanks!

Leon.
