Typedef Documentation
| typedef void(* lwip_cyclic_timer_handler)(void) |
Function prototype for a stack-internal timer function that has to be called at a defined interval.
Definition at line 61 of file timeouts.h.
| typedef void(* sys_timeout_handler)(void *arg) |
Function prototype for a timeout callback function.
Register such a function using sys_timeout().
- Parameters:
-
arg Additional argument to pass to the function - set up by sys_timeout()
Definition at line 84 of file timeouts.h.
Function Documentation
| void sys_timeout_debug | ( | u32_t | msecs, |
| sys_timeout_handler | handler, | ||
| void * | arg, | ||
| const char * | handler_name | ||
| ) |
Create a one-shot timer (aka timeout).
Timeouts are processed in the following cases:
- while waiting for a message using sys_timeouts_mbox_fetch()
- by calling sys_check_timeouts() (NO_SYS==1 only)
- Parameters:
-
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.
Definition at line 175 of file lwip_timeouts.c.
Variable Documentation
| struct lwip_cyclic_timer lwip_cyclic_timers[] |
This array contains all stack-internal cyclic timers.
To get the number of timers, use LWIP_ARRAYSIZE()
