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

[Frédéric Bernon]

Follow-up Comment #12, task #7490 (project lwip):

>Whether there is a size advised on creation or not is a separate issue,
although I think it would be good (as long as it is not a mandatory size -
some OS mailboxes are not configurable).

Yes, I think more to a way to configure these queues with different sizes:

netconn::acceptmbox (4-5 most of time)
netconn::recvmbox (large if some fast protocols are used)
tcpip.c::mbox (large enought to avoid any "blocked" states)

>Whether for 1.3 or not, I have no strong opinion, except that I know we're
already suggesting changes for after 1.3 that will break ports. So I think if
we ever want 1.3 to get out, we may just have to accept that 1.4 will break
ports again. 

Yes, it's true
