const int | lwip_num_cyclic_timers = (sizeof( lwip_cyclic_timers )/sizeof(( lwip_cyclic_timers )[0])) |
Stack-internal timers implementation. This file includes timer callbacks for stack-internal timers as well as functions to set up or stop timers and check for expired timers.
void sys_restart_timeouts | ( | void | ) |
Rebase the timeout times to the current time. This is necessary if sys_check_timeouts() hasn't been called for a long time (e.g. while saving energy) to prevent all timer functions of that period being called.
void sys_timeout | ( | u32_t | msecs, |
sys_timeout_handler | handler, | ||
void * | arg | ||
) |
Create a one-shot timer (aka timeout). Timeouts are processed in the following cases:
msecs | time in milliseconds after that the timer should expire |
handler | callback function to call when msecs have elapsed |
arg | argument to pass to the callback function |
void sys_timeouts_init | ( | void | ) |
Initialize this module
u32_t sys_timeouts_sleeptime | ( | void | ) |
Return the time left before the next timeout is due. If no timeouts are enqueued, returns 0xffffffff
void sys_untimeout | ( | sys_timeout_handler | handler, |
void * | arg | ||
) |
Go through timeout list (for this task only) and remove the first matching entry (subsequent entries remain untouched), even though the timeout has not triggered yet.
handler | callback function that would be called by the timeout |
arg | callback argument that would be passed to handler |
void tcp_timer_needed | ( | void | ) |
Called from TCP_REG when registering a new PCB: the reason is to have the TCP timer only running when there are active (or time-wait) PCBs.
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()
const int lwip_num_cyclic_timers = (sizeof( lwip_cyclic_timers )/sizeof(( lwip_cyclic_timers )[0])) |
Array size of lwip_cyclic_timers[]
