lwip_cyclic_timers

const struct lwip_cyclic_timer lwip_cyclic_timers[]

This array contains all stack-internal cyclic timers. To get the number of timers, use LWIP_ARRAYSIZE()

lwip_num_cyclic_timers

const int lwip_num_cyclic_timers = LWIP_ARRAYSIZE(lwip_cyclic_timers)

Array size of lwip_cyclic_timers[]
