[lwip-devel] [bug #1902] Timeouts and semaphores/mailboxes are too tightly integrated

[Jonathan Larmour]

Follow-up Comment #19, bug #1902 (project lwip):

Agreed on pretty much everything. I'm not sure you need OS specific constants
for "wait infinite" and "poll" though - instead give the functions different
names, and if the port wants to map that to the same underlying function with
special arguments, then it can do that with a #define.

As for 16-bit vs 32-bit timers. If we have a SYS_ARCH_MAX_JIFFIES, then I
think we have the tools to deal with frequent wraparound. Maybe we could
insist on 32-bit timers, but I'm aware that many hardware timers are 16-bit
only. As I said we can worry about the specific implementation some other
time (or if there's no demand, I guess never!).
