[lwip-devel] [task #7490] Add return value to sys_mbox_post

[Frédéric Bernon]

Follow-up Comment #3, task #7490 (project lwip):

>The problem that remains is that tcpip_input() can fail which results in
memory leaks

It's coherent with the current paradigm: sys_mbox_post should never failed,
and if the mbox is full, it should retry (inside sys_mbox_post
implementation).

I really thought it should be done after 1.3.0 to do a sys_arch redesign
where it's need. In a previous chat (I can't remember where it was), I
remember that someone (Jonathan perhaps) ask to also redesign sys_sem_xxx
functions.
