Re: [lwip-users] tcp_tmr and timers.c

[Sergio R. Caprile]

All I can tell you, and I don't know if it suffices, is that you call
        sys_check_timeouts();
in your main loop and all timing is done.
Check your lwipopts.h for the number of timers if using dhcp, dns, etc.
Should you need to use a timer for your own purposes:

static void myfunction(something *myarg);

        sys_timeout(SEND_TIME, (sys_timeout_handler) myfunction, myarg);
        // callback gets called back on timeout;
        sys_untimeout((sys_timeout_handler) myfunction, myarg);       
// timer removed
