[lwip-users] tcp_tmr - TCP_TMR_INTERVAL

[Hampus Thorell]

Hello!

I have some questions about the tcp_tmr(). I know this function calls 
two other timer functions but why are they needed?

In the documentation it says that it must be called every 
TCP_TMR_INTERVAL milliseconds. Does this imply that it must be called 
exactly every TCP_TMR_INTERVAL milliseconds or is it okay to call it 
more often than that? What happens if it isn't called exactly every 
TCP_TMR_INTERVAL milliseconds?

Best regards,
Hampus
